$1 s^{2}$ $1s^2$ $2 s^{2}$ $2s^2$ $2 p^{3}$ $2p^3$

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

The $1 s^{2}$ $1s^2$ is from the first period with Hydrogen and Helium.

The $2 s^{2}$ $2s^2$ 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 $2 p$ $2p$

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

The configuration is $1 s^{2}$ $1s^2$ $2 s^{2}$ $2s^2$ $2 p^{3}$ $2p^3$

Hopefully this helped!
