WebDec 15, 2024 · Well, in general, people will refer to the octet rule. For our second, third, fourth, fifth, and on and on shells, you're full when you have eight electrons. Eight electrons. The major exception to the octet rule is the first shell, where it is full with two electrons. So helium, even though it only has two electrons, is very, very, very stable. WebSep 23, 2024 · The valence shell is the outermost shell of an atom in its uncombined state, which contains the electrons most likely to account for the nature of any reactions involving the atom and of the bonding interactions it has with other atoms. Valence electrons are the outer-shell electrons of an atom.
