If the valence electrons were removed, what would be the ion charge of the element?

na =

-1
+1
-3
+3

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!

D-no effect on the rate

Of course: ) what’s your name ?
