WebHelium atoms have two electrons in their outer shell and the other noble gases have eight electrons in their outer shell. This is the maximum number that will ‘fit’ each shell, making the atoms stable. The current model depicts the electrons moving in space around the nucleus in a more cloud-like formation and not set in fixed shells.

WebNov 4, 2024 · Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell.
