#1s^2# #2s^2# #2p^3#

We need to find which period the element is in, and then which group it is in.

The #1s^2# is from the first period with Hydrogen and Helium.

The #2s^2# is from the second period Lithium and Beryllium.

Now we move onto the p-block in period 2. This means that our element will start with #2p#

Since nitrogen is the third element (behind boron and carbon), we have the exponent 3 after the 2p.

The configuration is #1s^2# #2s^2# #2p^3#

Hopefully this helped!
