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.
