This women here passed me in chemistry and I swear I'm crying.I can't thank you enough ur such a life saver!!! I went from getting Ds to As LIKE EVEN I CAN'T BELIEVE THAT ur so u underappreciated thank you so much :'))
This is the first time I actually understand something this from a chemistry teacher on TH-cam. Other people drag out their videos and make it confusing and hard to understand. You are such a blessing!
My teacher taught me this lesson today and I was just sitting there with my hands upon my head blinking. Thank goodness I watched this video. I swear this video was helpful.thanks
I haven't been understanding anything my teacher has been explaining to me so I went on youtube to get help and I am beyond thankful I found your channel. I actually have hope now that I will be able to pass chemistry! Thank you so much!!
My students would rather have her teach them. They're always asking for links to her videos to explain concepts 😂 Thank you for being my teacher assistant!
I was struggling in my chemistry class and I was just unmotivated to do my chem work but after watching your videos, I actually learned a lot more then what my teacher taught me and got more motivation. Right now im doing well in chem class. Thanks a bunch! I will def recommend your channel to my other friends who might be struggling in chem.
Thank you so much. You are amazing. I went from not understanding anything and thinking I'm absolutely trash at Chemistry to actually understanding concepts and being able to do calculations and ENJOYING it. I was ready to give up. Thank you.
Hey Melissa. I learned this in class the other day. I wanted to ask you a quick question. My teacher taught me that the atomic number is protons and electrons while the bottom number is protons and neutrons. Am I missing something and is is possible that I misheard this? Or misunderstood? Hopefully you can explain this to me. Thanks in advance!
@@0797cjm Atomic no is only equal to no protons but if you see in a neutral atom the protons and electrons are equal so only in a neutral atom the atomic no is equal to no of protons and electrons. And the bottom no itself is atomic number. So your teacher told this for neutral atom only.
I've researched the information provided to us at 6:12 and the number of electrons is actually 8. Also, by following your example whenever using the periodic table. Unless I'm missing something but the charge according to a notable website has indicated that is ( -1 ), which would give us the equation of 9 - ( -1) = 8 for the total of electrons.
When Fluorine is in its ion form meaning it shows a F- then yes this is true but that isn’t the question. This question is showing F in its neutral state this is why the number of protons and electrons would be the same since there is no charge shown.
Melissa Maribel awesome! I greatly appreciate that you took the time to explain that to me because I was following the steps provided and didn’t have the same answer. 🙂 Now, would you please explain the number of electrons for Oxygen and how you came to that conclusion? I’m having difficulty with that particular question at the moment. I’m simply doing this as practice on my own based on the set of rules that you’ve provided.
Hewwo Melissa...I am in grade 8 with so many chemistry problems...I started watching your videos from basic then gradually I understood every single thing which I couldn't understand by my teacher... MELISSA YOU'RE A LIFE SAVER....I ❤️ YOU AND YOUR VIDEOS...THANK YOU SO SO MUCH FOR HELPING US OUT!!!!😀😀☺️
Ms. Maribel, thank you so much for the help. I was so confused on chemistry at first. I love the videos, not only do you make learning look fun, you explain things so good and just make it fun. Thanks a bunch!
Hi, I just wanted to send a thank you from a thirty year old lady returning back to school after COVID changed some things. My final exam is tomorrow, and your videos have helped me have some confidence with math and setting up equations with Dyslexia.
When I was still in grade 9 (Currently on Grade 12) I would recommend Melissa Maribel to my classmates. She saved me during those days where I just cry because I don't understand chemistry. Thank you Melissa! You're a life saver
for 5:18 I got 10 for electron because the charge for "F" on my periodic table is -1. So I did ELECTRON = PROTON which is 9 - (-1) = 10 pls check if I'm wrong
thank you for your video! It has been very helpful. I do have 1 question, at the end, in the practice examples, how do you find the number of electrons in F without being given the atomic charge?
Melissa thank you so so much for these videos they are extremely helpful(: literally after a lecture I watch your videos, you explain everything so nicely and easy to understand ! (:
You are a really a lifesaver! U will surpass million subscribers very soon! Your videos help many students like me. Thank you very much for these wonderful videos !))
This is great, but am having difficulty finding the neutron, I don't seem to understand that part, I realized it during the practice question, I wasn't able to find the neutron as others
Rather than taking the time in class to show and break down this video, my teacher decided to set this as Cornell notes for hw. The only teacher who does this in high school is mind flipping blowing.
Now I am grade 10. Before I am seeing your videos I was struggled in all of the questions in chemistry but after I am watched your videos now I am fully understood the concept of every element,atoms,finding the mass number of element and so on. Thank you miss👍👍👍
How do we know if an element is neutral before finding the protons, neutrons, and electrons? In finding these for iron for example, I automatically subtracted protons from the charge but since it is neutral, the protons and electrons are equal.
Hi Ms. Melissa! I recently found your videos, about a month ago, and am reorganizing my Chemistry folder with a better understanding of Chemistry. I was wondering if you might know of anyone who explains things similarily to you (with enthusiasm) but discusses physics? Any help is greatly appreciated. If not, then it's ok. Thank you
I will be starting my chemistry class next week. I know forsure you will be a great help to me. Thank you in advance for the help. Not only are you very cute but also you're an awesome teacher!
Hi🙂 im incoming first yr BS Chem student and now im taking advance review through your tutorial videos, I hope to pass all my exams tnks to u in advance😘
If ur talking about the average atomic mass, Here is an example from my textbook:- Lets say we have 2 carbon isotopes, Carbon-12 and Carbon-13 and we want to find out their average atomic mass? The carbon-12 isotope has a natural abundance of 98.90% and Carbon-13 has an abundance of 1.10 percent. Step 1: Find the atomic mass of Carbon-12 : 12amu Step 2: Find the atomic mass of Carbon-13: 12.00335 amu (How did we find out? mass number = protons + neutrons) Step 3: Convert the percentage of natural abundances of each Isotope into a fraction - Carbon-12: 98.90/100 = 0.9890 - Carbon-13: 1.10/100 = 0.0110 Step 4: Calculate! (0.9890)(12 amu) + (0.0110)(12.00335 amu) = 12.01 amu This is ur Average atomic mass :) to check if ur answer is correct ur number should be in between the 2 isotopic masses and that its closer to the isotope with higher abundance. 🤍I hope this helps
Hey Melissa I love your videos and they really help me understand chemistry! Is it possible to do a video on Electron configuration, sub levels and orbitals ?
Can you please explain how to find the # of elements again? I followed your example but I am still having a hard time. For element "F", how did you come up with 9 as the number of elements? Thank you!!
It comes from the atomic number found on the periodic table, remember that the atomic number tells us the number of protons and electrons for a neutral (no charge) element. That's what I'm talking about at 1:32
SOS!! SOS I'm in serious trouble. Ms. Maribel, as usual, you are doing a great job. I need a favour. Can you please upload a video on Laws of Chemical Combination? The Law of Definite Proportions and Laws of Multiple Proportions are just killing me!! I need your help to survive. Give me some oxygen!!! Pretty Please. And sorry for the trouble..
This women here passed me in chemistry and I swear I'm crying.I can't thank you enough ur such a life saver!!! I went from getting Ds to As LIKE EVEN I CAN'T BELIEVE THAT ur so u underappreciated thank you so much :'))
That's incredible!! Congrats 🎉

hi there can you help me with the F one...I got the electron as 11 instead of 9....what's the charge?
Ms. Maribel, thank you so much for the help. I was so confused on chemistry at first. I love the videos, not only do you make learning look fun, you explain things so good and just make it fun. Thanks a bunch!
Thank you so much. I couldn't understand it at first.You are my new chemistry teacher
you have saved me from failing my exam i am forever in your debt
Ions are the hardest to remember but you helped A LOT 🥲
Such a great refresher for organic chem
I thought I was confused but no I now get it thank u very much
God bless you💙 I learned more watching your videos than sitting in my 3hr chemistry class
You made the concepts so easy😎😬
I'm watching all ur videos🎥

U make chemistry a lot easier for me thank you😁
Hi Ma'am your video it's been 4 years ago, and I can say that this video help me with my chemistry subject, I like how you explain it carefully
This woman is a SAINT. She makes up for all the less than chem professors out there
Hi mam ,your explanation is fantastic ❤️
I belongs from chemistry group but u r d best mam..! amazing 👍
Thank you so much!
You are such a blessing!!
for 5:18 I got 10 for electron because the charge for "F" on my periodic table is -1. So I did ELECTRON = PROTON which is 9 - (-1) = 10
pls check if I'm wrong
U saved my day...thank u Mam....
Hi! I got the answer to the first practice question, but I don't understand how to find the neutrons for the second practice problem.
thank you for your video! It has been very helpful. I do have 1 question, at the end, in the practice examples, how do you find the number of electrons in F without being given the atomic charge?
She doesn't miss! Another flawless class!
ngl your videos helped me pass chem 20, you explain the concepts so much better than my teachers
You made this so easy! I’m watching all your videos!!!
Wow you really helped me i didn't understand anything that my lecture was lecturing in class but now i do ❤️
Melissa thank you so so much for these videos they are extremely helpful(: literally after a lecture I watch your videos, you explain everything so nicely and easy to understand ! (:

Thank you so much for your help and resources. This is amazing
You are so welcome! Thank you for the support 💕
Thank u so much .Never had such a nice explanation 😀
this helped so much i loved the way you did the try it yourself problems !!!
you actually made me pass chemistry YOU ARE A GRADESAVER
Yay!! 🎉Congrats
Ms Maribel but what if I don't know the number of neutrons and the mass number?
What must I do first to find the number of protons neutrons electrons of fluorine
You’re so helpful, thank you!
Omg thank you so much Melissa. Your videos are always SO helpful. I can always go to your videos whenever I am struggling. You are an awesome teacher!
Hi Ms. Melissa! I recently found your videos, about a month ago, and am reorganizing my Chemistry folder with a better understanding of Chemistry. I was wondering if you might know of anyone who explains things similarily to you (with enthusiasm) but discusses physics? Any help is greatly appreciated. If not, then it's ok. Thank you
For the last practice/example, how do you solve or find out the exact number of the ion charge? I was a little confused lol
What about when you try to find the atomic number for something such as H2O? I have been stuck on that for a few hours
Thank you so much for existing hihi
Currently watching since my chem final is this Monday!
Thank you so much maam for good teaching , I learned alot about chemistry and how to compute 🥰🥰💕
I actually have hope in chem after watching your videos.
Yay!!! 🎉
Wow
Hi miss am new here now doing chemistry I find the way u break down the work is clear but having some trouble with solving the questions
I am so thankful to you, i passed my exams just because of you ❤❤
I will be starting my chemistry class next week. I know forsure you will be a great help to me. Thank you in advance for the help. Not only are you very cute but also you're an awesome teacher!
its 2021 now but I need help!!! I'm writing formulas. I have Ca +2 and SO4 -2, which is Ca2(SO4)2. Can I reduce that to CaSO2?
How do u know if it has a negative postive charge plz help me out
i LOVE the photo of you and John Dalton! #BFFgoals
I'm a new subscriber here and I really enjoy your videos! You help me understand!

How to get the electrons again?
i got 87 in chem 😊😊😊
Thanks to you mellisa......i passed my Examination.....
Your such a great Girl......
Thank you very much
Yay!! Congrats 🎉
@@melissamaribel thank you
lmao thx 4 the help i wasnt listening to my teacher lol
Wait my teacher told me that protons=electrons
Confusion 100%
👁👄👁
Love the intro and graphics.
Nice
Hi🙂 im incoming first yr BS Chem student and now im taking advance review through your tutorial videos, I hope to pass all my exams tnks to u in advance😘
0:26 That is gold!
You're the first one to notice! 😂Thank you Valeria, you are a gem 💕
how do you get a positive 2
Hey- i have a doubt how to find Atomic mass ?
If ur talking about the average atomic mass, Here is an example from my textbook:-
Lets say we have 2 carbon isotopes, Carbon-12 and Carbon-13 and we want to find out their average atomic mass?
The carbon-12 isotope has a natural abundance of 98.90% and Carbon-13 has an abundance of 1.10 percent.
Step 1: Find the atomic mass of Carbon-12 : 12amu
Step 2: Find the atomic mass of Carbon-13: 12.00335 amu
(How did we find out? mass number = protons + neutrons)
Step 3: Convert the percentage of natural abundances of each Isotope into a fraction
- Carbon-12: 98.90/100 = 0.9890
- Carbon-13: 1.10/100 = 0.0110
Step 4: Calculate!
(0.9890)(12 amu) + (0.0110)(12.00335 amu)
= 12.01 amu
This is ur Average atomic mass :) to check if ur answer is correct ur number should be in between the 2 isotopic masses and that its closer to the isotope with higher abundance.
🤍I hope this helps
You are my savior! Thank you so much for these informative videos!!!
This was really helpful. Thanks!
Ty this helped me so much!
thanks so much.....i love the way u explain am kings from Nigeria
I love this, it's so helpful
You're are doing a great public service with these videos, I appreciate you!
SO wonderfully helpful.
Hey Melissa I love your videos and they really help me understand chemistry! Is it possible to do a video on Electron configuration, sub levels and orbitals ?
These are so helpful! Thank you so much!
Ashleigh Tebo
what if you was only given the atomic mass and they asked you for how many neutrons does this iron isotope have
uhhh how do you find the charge of an element by looking at the periodic table, so you can find the number of electrons?
Thanks
Can you please explain how to find the # of elements again? I followed your example but I am still having a hard time. For element "F", how did you come up with 9 as the number of elements? Thank you!!
It comes from the atomic number found on the periodic table, remember that the atomic number tells us the number of protons and electrons for a neutral (no charge) element. That's what I'm talking about at 1:32

seriously thank you so much
Thx so much you’re amazing
Thanks a lot Mellisa
can you come teach at UALR our head professor is retiring and you're amazing!!!
Love you
SOS!! SOS
I'm in serious trouble. Ms. Maribel, as usual, you are doing a great job. I need a favour. Can you please upload a video on Laws of Chemical Combination? The Law of Definite Proportions and Laws of Multiple Proportions are just killing me!! I need your help to survive. Give me some oxygen!!! Pretty Please.
And sorry for the trouble..
Can u teach me how to calculate Ar
