8:14 congrats khan, you said "similarly" without chocking this time :) thank you as always

[@alvisworld8860]

Thanks sir

[@SeeratAnsar]

But what about trend of oxidation state Along period and along group??

[@WatchTheThrone23]

THANK YOU SO MUCH!!

[@mudasirrehman3605]

Thank you Great work ,,,,

They don't tell oxidation state of d block elements.

[@PwrEdits]

i would be interested in some videos on some economic topics if you would ever consider doing videos like that.

Doesn't oxygen typically have 8 elecrons? Carbon has 6.

[@LA-rp5uy]

This is 5 years late but NO it’s talking about it’s outer shell.

[@JayMark2049]

He means on the valence shell.

JayMark2049 Thank you. Isn't a cloud though, not a shell?

[@JayMark2049]

Verbal Swordsman By shell I mean the energy level. English isn't my first language so I might be misusing terms sometimes. Sorry about that. I'll try to explain better. Carbon has 2 orbitals (clouds); ''s'' and ''p''. It also has 2 ''shells'' (energy levels); 1 and 2. So its 6 electrons are configured as following; 1s^2, 2s^2, 2p^2. I use ''clouds'' to speak about orbitals (s, p, d, f) and ''shells'' to speak about the energy level ''n'' (1, 2, 3, 4 etc).

[@berny88925]

Oxygen has 8 but 2 of them are used in the first cloud, or shell, and the other 6 left over are on the second cloud or shell. That cloud wants to have 8 in total to be filled up so its missing 2. It's going to try to get the other 2 electrons from anything that it can oxidize. The closer the elements are to filling their outer shell, the more "electronegative" they will be. meaning that they will take other electrons more aggressively because they are desperate. Since oxygen only needs 2, its really desperate for another 2, so it takes almost any other elements electron. In this case its hydrogen. It takes 1 from hydrogen, but since hydrogen also wants an electron, it will try to hog on to it. When you have 2 of these its water (H2O), but other times a hydrogen just lets its electron go, and becomes an Ion. The Oxygen and other Hydrogen stay attached and it's called a Hydronium Ion, because it kept the other hydrogens electron, so it is more negative, while the poor hydrogen lost it's electron, so it becomes an ion as well. Just a proton which is over all, positive. :) Every element wants to have its outer shell either filled, or clean, so for some its better to give away an extra electron, for some its better to take.
