Question #6539f

Answer 1

The central atom is `"N"`.

Explanation:

You have two choices for the connectivity:

`"N-N-O"` or `"N-O-N"`

The general rule in drawing Lewis structures is:

The less electronegative atom is the central atom.

`"N"` is less electronegative than `"O"`.

Thus, `"N"` is the central atom, and you start with the atoms joined in the order `"N-N-O"`.
