A Tour of the Periodic Table

[@mahlawat12]

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.

Thank you! You're videos are helping me study for my nursing entrance exam! Much appreciated.

[@SarahStarmer]

N5 Chemistry in Scotland numbers the groups from 0 to 7 missing out the transition metals. Also, not all gallium is radioactive.

[@colombianmami61]

Thank you Mr. Andersen for this youtube lesson! :)

[@GianmarioScotti]

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.

[@Richnz00]

Correct. Also far less toxic than mercury.

[@markswift]

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.

[@sedonaportal]

Thanks. Easy to understand explanation of the Table. Love the highlighter pen and photos.

[@jeffrey6244]

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 :)

Mr. Anderson, what video software are you using to create this video? btw love the video!

[@NARKISDUDE]

2:35 wait so 87 belongs on that group or not?

[@prashastyjkarki5689]

It does. Francium is the most reactive metal

[@Christy777222]

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?

[@hiimapotato]

use the numbers

[@GamerNation1234]

[@katrinagregorio1108]

what video maker do you use! awesome vid btw! helped me a lot ... way better than most of periodic table vids ive watched =)

[@hihi176100]

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.

[@KarbineKyle]

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.

[@lorasingun2651]

Thank you very much Bozeman Science. Your videos are very helpful.

[@afpskierx]

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.

[@francishughes81]

this was a lifesaver, thank you so much!

[@loverboykmangambit7562]

This was very helpful thinks mr:Andersen

[@reesew71]

"Galium is highly radioactive" are you sure about that

[@TheWadetube]

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.

[@nicoya_beauty]

Thank you for doing this! I homeschool my kids and this helps out so much!

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!

[@iEatTreeSap]

Thank you for helping me with my Chem assignment!

[@StevenTorrey]

Excellent!

[@sinekonata]

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?

[@jojocatty]

+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 ;)

[@endimion17]

No isolated compounds have been made, but certain ions and excimers have been detected. Therefore, they're not completely inert.

[@carolinawilson9693]

just ordered the book! so excited to read it!

[@Basicname-sq8wo]

very well explained thank you

[@kailynnecazem8726]

I'm not learning this in chemistry yet but I like to learn more about what chemistry is about.

[@kooksies5712]

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.

[@ssymck]

love your work really helps a lot BIG THX

[@ienehanceit]

i liked the video just by seeing the thumbnail,later saw the video

[@teach623]

gallium is completely safe and readily available to the public. not radioactive whatsoever...

[@jonathancataldo276]

+Tim Miller Some isotopes of gallium are radioactive but the most common are stable. So go on play with it. :)

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.

[@clemmiemayhew456]

You come here when you're meant to be learning the periodic table, but instead you're watching somebody else learn it.

[@hiimapotato]

From lithium at the top to cesium (Has Fr highlighted under it)?

[@honestube2671]

Yeah, that's what I'm confused about... Is Fr an alkali metal, or is it just accidentally circled or not said?

[@omarmian4222]

It is an alkali, one of the most reactive ones, he just forgot to mention it

[@minniekim2351]

you are so amazing! thanks a lot!! from korea

[@timewasteland]

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.

[@fnagonyoutube]

well that ended unexpectedly

[@osvaldobarrios2861]

Great video I like it you make more sense than my teacher

[@TheWadetube]

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.

[@ld2-gold578]

The Videos from 2010 really helping? Well ofcourse

[@kooksies5712]

helium and neon are completely inert actually. the rest of the noble gases will react with fluorine under certain conditions.

[@GeorgiaTheFabulous]

thanks for this. helped me heaps

[@endimion17]

They are combined using covalent bonds,but they're short lived.We can't call them inert just because of that. A compound is not term used exclusively for stuff we can scoop with a spatula,pick up with a pipette or transfer using a gas syringe. That's why we say helium and neon are inert "under standard conditions",but not absolutely inert per se. However,errors in this video are much greater than in this small detail and that's bad because the channel is presented as an authority on the matter.

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 :)

[@ラットキッド]

I’m here from summer homeworrkkkk.... :D

[@alecsaguilan]

thank you very much!

[@colombianmami61]

Actually, both of you are correct but since transition metals can vary in the number of valence electrons (which he states), some periodic tables show groups 1A, 2A 3A 4A 5A 6A 7A 8A and the transition metals are 3B or listed in Roman numerals. Other tables, like the one shown in this video go from 1 -18. Please do some research before you confuse others.

[@muhammadtaha2554]

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

[@silverfang1855]

are lanthanides and actinides part of the rows?

He should have said that all of those elements have completed (or full) shells - meaning that they are non-reactive.
