The central atom is $\text{N}$.

#### Explanation:

You have two choices for the connectivity:

$\text{N-N-O}$ or $\text{N-O-N}$

The general rule in drawing Lewis structures is:

The less electronegative atom is the central atom.

$\text{N}$ is less electronegative than $\text{O}$.

Thus, $\text{N}$ is the central atom, and you start with the atoms joined in the order $\text{N-N-O}$.
