2021.. after a decade he is still the best chem teacher. Helping students like me across the globe. I am preparing for a hardass exam and this is the most helpful channel I have come across. Incredible. Better than any paid course or even Uni professors. This channel should be trending now because of Covid and online classes boom.
Fascinating! I tutor an 8th grader in Science, and this is perfect for her. Thank you for the tip on the alkali metals in water videos, so awesome! She'll love that.
I just finished reading "The Disapperaing Spoon." It is an excellent book. I am currently reading "The Violinist's Thumb." Sam Kean and Mr. Anderson should create textbooks together.
You need to update this video to include the several elements near the end that have been discovered since you made this. I like the fact that you put Lutetium and Lawrencium in their correct places among the transition metals, however these two series are now called the Lanthanoids and Actinoids. Polonium is sometimes considered to be a post-transition metal, but I like it as a metalloid because it completes the stair-step pattern :)
my thoughts exactly! I'm actually watching this as a required assignment for chemistry class and I have gallium at home. Curious how this slipped by my teacher...
Gallium isn't radioactive. It has unstable isotopes, but all elements do. Some are naturally occurring, and others are produced synthetically (proton, neutron, or heavy ion capture). There are Plutonium-Gallium alloys, which are used in reactors though.
Question: where exactly are the lanthanides and actinides inserted into the periodic table? Is the order 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 5d1 4f14 5d9 6p6? So are they after the first column of the d block, or before the d block? In the periodic table showing in the beginning, you have 15 elements in the f block. This isn't possible as there can only 14 f block elements. Why do some periodic tables show it this way?
Sometimes if parents are smart or their kids get bullied they just homeschool them:) And they do make Homeschool co-ops, they're like one day a week private schools so that they DO socialize. And I know a homeschooler, and they are probably the smartest person I know... so good on you Nicoya!
8 groups if you're talking about the specific groups like the transition metals, alkali metals etc. There are 18 'groups' or families, as in the columns. I guess he used them interchangeably.
Thanks for making the table more regular to me by explaining that the last 2 rows should be a lot longer :D Also why isn't [Al] a metalloid? And finally are the 2 loose rows transition metals as well?
+sinekonata Hello! 1.Aluminum(Al) is a metal since it's shiny, ductile and malleable.Also, it loses valence electrons(just like any metal), and is a solid at room temperature. 2.The last rows are called Lanthanides (1st row down) and Actinides (2nd row down).They are called "inner transitional metals".One reason they are separated from the rest is because they have an f orbital.To make the periodic table simpler and more organized ,they placed the elements in a way that the s,p,d and f orbitals elements are beside each other. Wish that helped ;)
Every atom has valence electrons, unless it has no electrons at all (such as ionized hydrogen). The definition of a valence electron is simply an electron that is capable of forming a covalent bond. Though the noble gases are not apt to do so under normal conditions, they can form bonds if their electrons are excited to a high enough energy level. Xenon is particularly easy to form bonds with in respect to the others.
But isn't valenselectrons just a name for the electrons located in the outer shell? Even if there are eight electrons in the outer shell, it's still eight valenselectrons, since the outer shell is also called the valens shell, right? I may be wrong though, haven't really read into this enough yet.
I believe that Gallium is not radioactive, but rather the Isotope Gallium 67 is. Regular metallic Gallium is considered non-toxic to the body, but Gallium salts can cause renal trouble.
that is quite interesting actually. my understanding of 'inert' in a chemistry context means an inability to chemically react, i.e. form covalent/ionic bonds with another element. When you ionise elements it doesnt mean they are chemically active, nor does the fact they can form excimers.
Also, I believe that the noble gasses all have a filled outer electron shell, not 8 valence electrons, for helium has only a couple of electrons up to 4 and radon has a large outer shell capable of 18 or more, I would have to look it up.
You made a boo boo on the noble gases. You said they all have 8 valence electrons, that was incorrect Helium only have two but there do belong in the column because the outer energy level are complete.
Hey guy answer my question if helium has two electron in its last shell so its balance but it should be on 2nd group 1 shell 1 period is true but how its noble
It's not really, only in 8th grade. (Well, where I live it is) and that only lasts a couple weeks at most. I promise it isn't hard to memorize these things if you study (And then you get to forget them after :)
Groups only go to 8/ 0 as they represent the amount of electrons in the outer shell except 8 known as 0 as it has a full outer shell. transition metals don't have groups as they can gain ions and things xxx
Thanks for the video. Gallium is radioactive (claim at 1:50)??? The Wikipedia article indicates that gallium is a mixture of two STABLE isotopes, and is not radioactive.
This man is amazing. I wish TH-cam had been around during my college years...would have saved me many tears.
very true
britishTRIGGERED chick 9th as in high school? Cause me toooo
I'm left with a week to start my final exam,I need more information on chemistry...I don't know where to start
Same thought!
Let me tell you, It doesn’t change a fucking thing about college. Still sucks ass

I was waiting for you to start with the tour when you were talking about the book but it was definitely worth the wait! Thank You! =D
The Disappearing Spoon is one of the best books I have ever read, in my opinion. I love it!
I just finished reading "The Disapperaing Spoon." It is an excellent book. I am currently reading "The Violinist's Thumb." Sam Kean and Mr. Anderson should create textbooks together.
Thank you! You're videos are helping me study for my nursing entrance exam! Much appreciated.
Thanks. Easy to understand explanation of the Table. Love the highlighter pen and photos.
N5 Chemistry in Scotland numbers the groups from 0 to 7 missing out the transition metals. Also, not all gallium is radioactive.
We LOVE Mr. Andersen!!!!!!

Roses are red, violets are blue I came here to study, so did you
No I came here for the meme
I came to read your comment
Me too
I actually didn't I was just interested in it.
Gallium is NOT radioactive! In more detail: the naturally occurring gallium is composed of two isotopes, Ga-69 and Ga-71 - and both are stable.
Correct. Also far less toxic than mercury.

my thoughts exactly! I'm actually watching this as a required assignment for chemistry class and I have gallium at home. Curious how this slipped by my teacher...
Darn it I was just about to say that.
My thoughts!
Thank you Mr. Andersen for this youtube lesson! :)
Thank you sooooo much I had a hard time understanding the periodic table. Will watch again and take notes before class starts!
He seriously messed up the metals and non metals separation part
HI 4 years
@@br3ys3n16 lol.... but wha- like- i have a test today.... did he do something wrong?
@@zuzuderose1246 what grade are u in?
How
Damn it’s been 4 years since I commented this, and I don’t even remember doing it
CAME TO STUDY, LEFT SUBSCRIBED
@ 0:52 I thought he was making a smiley face
same wtf
me too
same lol
me tooooooo
I always hated chemistry... It's intimidating like hell
I have seen a number of videos handling gallium, so I think it is not normally radioactive
Cool! this helps me remember all the things I forgot again!
i liked the video just by seeing the thumbnail,later saw the video
Nice work, good communication skills.
Thank you for helping me with my Chem assignment!
This was very helpful thinks mr:Andersen

use the numbers
Excellent Excellent Excellent explanation....please keep it up and and upload similar stuff...
Thank you for doing this! I homeschool my kids and this helps out so much!
Nicoya_Beauty why?
You shouldn't they need a social life.
Sometimes if parents are smart or their kids get bullied they just homeschool them:) And they do make Homeschool co-ops, they're like one day a week private schools so that they DO socialize. And I know a homeschooler, and they are probably the smartest person I know... so good on you Nicoya!
just ordered the book! so excited to read it!

This was very helpful, thank you for that :)
this was a lifesaver, thank you so much!

Hello!
1.Aluminum(Al) is a metal since it's shiny, ductile and malleable.Also, it loses valence electrons(just like any metal), and is a solid at room temperature.
2.The last rows are called Lanthanides (1st row down) and Actinides (2nd row down).They are called "inner transitional metals".One reason they are separated from the rest is because they have an f orbital.To make the periodic table simpler and more organized ,they placed the elements in a way that the s,p,d and f orbitals elements are beside each other.
Wish that helped ;)
Thanks.Your keeping our science straight. Thanks
Thanks will be taking chemistry for the first time I never took this subject in high school so this is a need introduction to the periodic table.
"Galium is highly radioactive" are you sure about that
Every atom has valence electrons, unless it has no electrons at all (such as ionized hydrogen). The definition of a valence electron is simply an electron that is capable of forming a covalent bond. Though the noble gases are not apt to do so under normal conditions, they can form bonds if their electrons are excited to a high enough energy level. Xenon is particularly easy to form bonds with in respect to the others.
2:35 wait so 87 belongs on that group or not?
It does. Francium is the most reactive metal
you are so amazing! thanks a lot!! from korea
Mr. Anderson, what video software are you using to create this video? btw love the video!
Excellent!
But isn't valenselectrons just a name for the electrons located in the outer shell? Even if there are eight electrons in the outer shell, it's still eight valenselectrons, since the outer shell is also called the valens shell, right? I may be wrong though, haven't really read into this enough yet.
If the energy of hydrogen can be calculated with Rydberg constant, how can the energy of the other 117 chemical elements be calculated?
Science Homework is Lit
Awesome! Thanks a million !
And just like that we’ve gone across the whole universe
I'm not learning this in chemistry yet but I like to learn more about what chemistry is about.
From lithium at the top to cesium (Has Fr highlighted under it)?
Yeah, that's what I'm confused about... Is Fr an alkali metal, or is it just accidentally circled or not said?
It is an alkali, one of the most reactive ones, he just forgot to mention it
Great video I like it you make more sense than my teacher
I believe that Gallium is not radioactive, but rather the Isotope Gallium 67 is. Regular metallic Gallium is considered non-toxic to the body, but Gallium salts can cause renal trouble.
I came here to do late summer homework bc my mom is going to beat my ass if I fail and I have an 18 in science
felt that
that is quite interesting actually. my understanding of 'inert' in a chemistry context means an inability to chemically react, i.e. form covalent/ionic bonds with another element. When you ionise elements it doesnt mean they are chemically active, nor does the fact they can form excimers.
what video maker do you use! awesome vid btw! helped me a lot ... way better than most of periodic table vids ive watched =)
very well explained thank you
Your so smart and kept my interest throughout the whole video!! You got my subscription thank you this helped for my final so much!!!
Also, I believe that the noble gasses all have a filled outer electron shell, not 8 valence electrons, for helium has only a couple of electrons up to 4 and radon has a large outer shell capable of 18 or more, I would have to look it up.
Thanks for your time to make such good education vedio. I use it teacher my son.
You come here when you're meant to be learning the periodic table, but instead you're watching somebody else learn it.
love your work
really helps a lot
BIG THX
hiiii
can you tell me please what ddi you use to make this video what is that tool you use to appear on screen like a black board???
on the transtion metal of group 2B is like that Zn are similar with group 1A
Can u explain what u mean by valance -and explain how lost and gain electrons
amazing Sir
you teach very well
Love his so informative - I learnt to much .
Thanks. Try list-twist for the elements
How did he screen record and show cam at same time 11years before 🤧
This is awesome!! Very helpful... Thank you :)
What are elements Uun and Uuu? I know what Uub and Uuq are but what are the elements Uun and Uuu?
No isolated compounds have been made, but certain ions and excimers have been detected. Therefore, they're not completely inert.
Thankyou... niga adipoly aanettaa
are lanthanides and actinides part of the rows?
The Videos from 2010 really helping? Well ofcourse
can you do one about metals and non-metals
Świetny film
excellent video!
Gallium is not radioactive but there might be other isotopes of it that are but I ordered some online and its not
thanks for this. helped me heaps
"Galium is highly radio-active"
youtube trend in 2018 : oh shit
great vid...clean and articulate!!
I though Polonium was a metal and Astatine was a Metalloid?..
good explaination about elements n their place in peroidic table
God.... e w e You just gave me a better chance at passing my Science Test....
How are u doin after 8 years?
well that ended unexpectedly
What about Uub and Uuq at the bottom
You made a boo boo on the noble gases. You said they all have 8 valence electrons, that was incorrect Helium only have two but there do belong in the column because the outer energy level are complete.
Where's the rest of the video? I want to learn
Hey guy answer my question if helium has two electron in its last shell so its balance but it should be on 2nd group 1 shell 1 period is true but how its noble
Just skip to 1:50 if you don't wana hear about spoons
I’m here from summer homeworrkkkk....
:D
It's not really, only in 8th grade. (Well, where I live it is) and that only lasts a couple weeks at most.
I promise it isn't hard to memorize these things if you study (And then you get to forget them after :)
The guy is teaching us how to recognize trends of the periodic table. Not drool over it.
Groups only go to 8/ 0 as they represent the amount of electrons in the outer shell except 8 known as 0 as it has a full outer shell. transition metals don't have groups as they can gain ions and things xxx
Groups go till 18. Transition metals certainly do have groups.Elements of the same period have the same number of electron shells.
Thanks for the video. Gallium is radioactive (claim at 1:50)??? The Wikipedia article indicates that gallium is a mixture of two STABLE isotopes, and is not radioactive.
no, helium doesnt have 8 valance elektrons, but only 2 (1s*2)
What are you on about?
Using this for homework
Do we need ALL of this for GCSE
What software do you use to make these?
