Incredible. Better than any paid course or even Uni professors. This channel should be trending now because of Covid and online classes boom.

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 :)

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.

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.

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.

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?
@jojocatty8 жыл бұрын
+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 ;)

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.

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?

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.

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
