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. WebShell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons. As you learn about elements …
