Question

Why can an atom only have 8 valence electrons?

Answer 1

Answer:

I understand that for most molecules, the goal is to reach the octet rule. There are exceptions such as Hydrogen where its max is only two. I am getting lost when it comes to molecules with atoms taking more than an octet. Can someone maybe give an example and explain when and why certain exceptions allow an atom to have more than 8 valence electrons.

Answer 2

Answer:

Atoms with 8 electrons in their valence shell have completely filled last orbitals and are therefore the most stable, as their electronic configuration is similar to that of the closest noble gas. The number 8 is a lucky number, according to many Asian cultures
