Step-by-step explanation:
There are different ways to express the electronic configuration of zinc.
We are going to use the shell notation and the sublevel notation.
Zinc as an element belongs to the transition metal groups found in the d-block of the periodic table.
The element is made up of 30 electrons.
Shell configuration = 2 8 18 2
Sublevel notation = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s²
