Question

What is octant number?

Answer 1

octet number?

Answer 2

I don't really know. I think yes :)

Answer 3

The octet rule is a chemical rule that states atoms of low (<20) atomic number tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electronic configuration as a noble gases.

Metals tend to lose electrons to achieve octet rule, say, magnesium has an electron configuration of 1s2 2s2 2p6 3s2, magnesium loses 2 electrons from 3s2 turning into
1s2 2s2 2p6 which the second shell has 8 valence electrons and achieved octet rule.

Electrons and shells (Magnesium)
2.8.2 turns into 2.8

Answer 4

Okay, thanks, i'm trying to digest it :) here's a medal btw.
