# What is the electron dot diagram for zinc?

Jan 13, 2017

The electron dot diagram for zinc is $\text{Zn:}$

#### Explanation:

Zinc (element number 30) is in the 4th Period of the Periodic Table.

From left to right, you count two $\text{4s}$ electrons and ten $\text{3d}$ electrons.

The $\text{3d}$ shell is a filled inner shell, so only the $\text{4s}$ electrons are valence electrons.

Thus, the electron dot structure for zinc is $\text{Zn:}$
