@@melissamaribel you are the best best best chemistry teacher ever,because of our chemistry teacher many people are dropping science class and going for economic because of how hard and boring he is but I think I am getting hope now after seeing your channel thank God and I will share with my fellow science classmates
She forgot to mention something very important regarding the Ionization Energy part; Another exception other than the two she named is that the NOBLE GASES are going to have the HIGHEST ionization energy since they are so stable it is going to require the most energy to remove an electron.
@@harmie1743 No, because now another component has to be taken into consideration; orbit size. The bigger the orbit the less energy it’ll need to removed an electron since it’s so far away from the nucleus now and the smaller it is the harder it is to remove an electron since it’s closer to the nucleus. So when you are going down the noble gases periodically they get bigger and bigger thus less IE. Therefor the most IE will reside with the noble gas of Helium.
Yes! I’m going to ask my professor why she explained electron configuration so difficulty when that video maribel showed simplified it and I learned how to do it in 10 minutes
Watching this for my test tomorrow. I have learned from this more than from our class. Everything is now clearer to me. Thank you so much for your discussion!
18:12 - one way I can recognize which is larger is because Br has 35 protons while Kr has 36 protons, the 35 protons in the Br nucleus is going to have less of a pull to the 36 electrons compared to the pull of Kr's 36 protons so Br will be larger. Understanding this requires understanding the shielding effect, but for me it's helpful to know the why behind anions being larger.
This whole Channel is a life saver. My chem teacher is not the best so I never understand anything unless I ask a billion questions. This video helped me a lot with my homework because my teacher told us to figure it out basically.
wow I watched about 5 different videos about periodic trends and not one of them helped me... until I seen yours! you break it down so easy for me! thank you!
I just want to express a heartfelt THANK YOU. 💕 Going through your videos makes me feel like you are holding my hand and encouraging me not to quit and you dont even know me.
I believe the electronegativity follows the below order. Ne > F > O > N >= Ar > C > Kr > Cl > S >= Xe > Se ~ I ~ Rn> other elements..... Helium's EN is very difficult to predict. Its should be less than that of oxygen.
your videos are saving my life during quarantine right now! my chem teacher is posting your videos to help us learn, and it makes not having a teacher there so much easier. thank you!!
Melissa, I really have no words to explain my gratitude to u right now. But if u were standing next to me right now I would hug u real tight and say "Thanks for saving my life, Superwoman."
I have been looking through my chemistry book for over 2 hours now, I asked the teacher, and searched everywhere on how to calculate the ionization energy and what are the exceptions, you were the only one who explained it very well and simply, I thank you so much. btw if you were interested the question I had, it was: In which of the following does the second element have a lower first ionisation energy than the first element? a)S. O b)Li. Be c)Mg. Al d)Si. C and from what I understood from the video the answer should be c). please correct me if I am wrong thank you.
Thank you very much Ms @Melissa for using the banal concepts to understand us . This was my second video on your channel and I love spending time because of the concepts that were concealed for so long. Appreciate your efforts! Keep up the good work!
I was so confused with my virtual experiment since my teacher explained it differently. I tried to watch videos online and this helped a lot. I can now understand most of the things he taught us! Still, a bit confused but I gathered the most important ideas thank you.
yo i appreciate you infinitely. You are aesthetical, have a great philosophy for how you teach, organizational, communicative, and concise. Realy bang up job Meelissas
Lord i have been saved 😭 i studied this topic both at school and tuition but i just could not get it. They over complicated it so much. Tomorrow is my chem exam and i feel alot more confident about this chapter, all thanks to you! You're a fantastic teacher 💞
thank you thank you thank youuuu!! I can barely keep up understanding chem during online school and everything is going way too dang fast but you were so direct and talked more in-depth as to reasons why certain things happen so thank you so so much !!
Great video. I love how much knowledge I got from just roughly 20 mins. You're out here competing with the likes of The Organic Chemistry Tutor !!! You two are great!!
I have so many doubts I this chapter before watching this video but my all doubts are cleared after watching this video thank you ma'am so much for this video 😊
My summer Chemistry 1 professor gives us links to your videos instead of him posting lecture videos. That's how you know you have a great way of explaining things.
I’m so glad I found you on TH-cam, I don’t know how I would pass chemistry without your videos😭😭. I have a test on this tomorrow and I’m pretty confident now after watching you video. You are so helpful, thank you soooo muchhh!!!❤️
Thank you so much for the lesson, understood it like a gem. I'd like to add a suggestion regarding the questions: I think you should add complex comprehensive questions as well or more of a diversity because there was really two distinct structural questions. One, that was about this element vs. this element, two, was about ordering elements in ascending order due to their properties. I reckon if you added perhaps two other indefinite structural questions, it would challenge the understanding of the viewer. Anyway, thank you :) Your videos are very helpful in terms of learning the content. I will start chemistry this year with the knowledge you gave to me, which in that, is powerful.
I think all tutors should be teachers because tutors actually WANT to help a student understand their work! “Regular teachers” just kinda stand at the front of the classroom or lecture hall and blubber about whatever, and don’t seem to care if students understand anything or not because it’s “not their job to learn because they’re not the student” (lol okay what?)
I just want to say that I really liked how nice your voice sounded(I know I sounded creepy, but it's true). Plus, this video actually helped me understand a lot than my current Chemistry teacher because we're doing a lab on this and he gave it to us without any learning about it whatsoever. So really, you've done a great job explaining all the different periodic trends. I was able to learn so much thanks to you! :)
thank you so much for this, you explained everything so well and went into depth about the reasoning behind everything. I struggle with chemistry because I usually just try to memorize rather than understand, but I could grasp everything you taught here!!
I learned alot in this video compared to my teacher's discussion lol. I always fell asleep on his class because his voice makes us really sleepy. Thank you! You saved my life and my grades.
Hi! I absolutely love your videos! (Especially the night before an AP Chem test😉) We are covering one of the last few chapters before the big AP Exam aaah!! I was wondering if you could possibly do a video covering Chemical Thermodynamics? More suggestions would be electrochem or organic chem. Thank you!
You just save me from my deepest misery... I finally now have the confidence to solve every problem that my Professor will give to our Prelim Examination... This video is very interesting and well- explained and detailed... Love it SO MUCH!!!
You are so helpful and amazing. You have helped me so much. The way you teach is amazing. Again, just wanted to let you know what a difference you are making.
Hello Melissa Your TH-cam site was recommended by my son's high school teacher. I was a life saver last year! He passed with an A. He truly learned chemistry and your videos helped everything make sense. I have another son who is in college and is struggling with University Physics. Is there any one or TH-cam site you can recommend for him? I would be so grateful. Thank You!!!
I have a AP CHEM Test today. I’m using these videos as review and refreshers. I predict I will pass. I will come back after I do it and comment my grade. 🤞🏻
How will this gonna solve. The active ingredient in one brand of antacid is magnesium oxide , MgO( Molecular Weight= 40.31g/mol). If it is dissolved in 250mL water at a ratio of 1:10, how many grams of MgO must dissolved in the solution?
I literally have COVID and my chem teacher was like “haha I’m not gonna post anything for you to do oh now you have all of these assignments!” I want to drop out and cry
That’s horrible!! I’m so sorry you are going through that 😔 I recommend reporting this to the department and if possible, getting a parent involved. No one deserves this kind of treatment. Wishing you a speedy recovery Kenzie ❤️

Hi
She forgot to mention something very important regarding the Ionization Energy part; Another exception other than the two she named is that the NOBLE GASES are going to have the HIGHEST ionization energy since they are so stable it is going to require the most energy to remove an electron.
Do the noble gases follow the same vertical trend (higher row the noble gas is, higher IE compared to lower noble gases?
@@harmie1743 No, because now another component has to be taken into consideration; orbit size. The bigger the orbit the less energy it’ll need to removed an electron since it’s so far away from the nucleus now and the smaller it is the harder it is to remove an electron since it’s closer to the nucleus. So when you are going down the noble gases periodically they get bigger and bigger thus less IE.
Therefor the most IE will reside with the noble gas of Helium.
@@erikacorona7413 u just saved my chem grade
Why did she calculate the ions or electrons or whatever? Isn't the largest cation, the smallest ion size?
Nevermind, I think that I understand now.
