Answer:
Six electrons or three pairs.
Step-by-step explanation:
Six electrons are shared by both atoms of nitrogen molecules because both needs three electron to become stable. They formed covalent bond by sharing of electrons with each other and attain stability. Ionic bond can't formed between two nitrogen atoms because very high amount of energy is required to remove and add electrons in the valence shell. So they share 6 electrons or three pairs of electrons with each other.
