2^+

Explanation:

Atomic number of Zinc is 30.
So, according to octet rule(2n^2),

Maximum electrons in shell K ->2
Maximum electrons in shell L ->8
Maximum electrons in shell M ->18

Number of electrons left for shell N, is 30-28 =2

Therefore Zinc need to get rid of 2 electrons and it will become a 🐈ion.

So, the valency of Zinc cation is 2^+Wikimedia commonsWikimedia commons
