Hi!
As N atom has 3 valence electrons, we can realize that it shares 3 electrons with O atom. By drawing the lewis structure we can find out that it forms a double bond and a single bond with the oxygen atom.
By forming each of the bonds it shares an electron. As it forms 3 bonds(a double bonds and a single bond), it shares 3 electrons.
