Answer 2

Answer:

3

Explanation:

As hydrogen can only ever have 1 bond to/from it, we can say that nitrogen is the central atom with hydrogens around it. As covalent bonds involve the sharing of electrons, and there are 3 covalent bonds, nitrogen shares 3 of its 5 outer electrons, 1 each with the 3 hydrogens, and so there are 3 bonding pairs.
