WebAug 15, 2024 · The octet rule doesn't actually say the highest shell should have eight electrons. It says that the atom achieves stability by gaining the electronic configuration of the nearest noble gas. Noble gases have the general configuration s 2 p 6 ( 8 electrons?), but as demonstrated above, these 8 electrons may not be in the highest shell. WebThe configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior.
