Electronic configuration of Na is:
1s2, 2s2, 2p6, 3s1.

If valence electron i.e electron from 3s orbital is removes, sodium will have configuration same as Neon with a +1 charge on it.
Hence charge on the ion will be +1.

Hope this helps!

Answer:

+1

Explanation:

Sodium is the element of first group and third period. The electronic configuration of sodium is - 2, 8, 1 or \(1s^22s^22p^63s^1\)

There is one valence electron of sodium.

If sodium loses one electron, then it will attain the noble gas configuration of neon and become stable. By losing one electron, it will become positively charged.

Thus, the charge on sodium element will be +1.
