Yep!
the abbreviated electron configuration of sodium is (Ne) 3s1
1s2, 2s2, 2p6, 3s1. It the the '3s1' electron that readily ionises m because it is in the outer most electron energy shell.

The noble gas configuration of a sodium ion (Na+) is the same as that of neon. This means that the electron configuration of sodium ion is [Ne] where [Ne] represents the electron configuration of neon.
The electronic configuration of a sodium atom is 1s2 2s2 2p6 3s1. This means that sodium has 11 electrons distributed across its energy levels.
