Answer:
1 unshared pair of electrons
Explanation:
In order to draw the Lewis structure, we need to consider the octet rule: atoms tend to share electrons to complete their valence shell with 8 electrons. In the case of H, it has to complete a duet (2 valence electrons).
N has 5 valence electrons, so it has to share 3 pairs of electrons to reach the octet.
H has 1 valence electron, so it has to share 1 pair of electrons to reach the duet.
In the picture, we can see the resulting Lewis structure. There is 1 unshared pair of electrons on each nitrogen.
