Na has a ground-state electronic configuration of

1 s^{2} 2 s^{2} 2 p^{6} 3 s^{1}

Removing the 3s electron leaves us with the noble gas configuration

1 s^{2} 2 s^{2} 2 p^{6}

, so a sodium ion is Na+.

Electronic configuration of

N a

is 2, 8, 1. One electron is removed for the formation of

N a^{+}

So the new electronic configuration is 2, 8.

Hence, 1st(K) and 2nd(L) shells are completely filled.
