When two nitrogen atoms bond together in n2, what type of
covalent bond do they form?

a) a double bond, because they overlap orbitals to share two electrons.

b) a double bond, because they overlap orbitals to share two pairs of
electrons.

c) a triple bond, because they overlap orbitals to share three electrons.

d) a triple bond, because they overlap orbitals to share three pairs of
electrons.

The correct answer is D). See the explanation below, please.

Explanation:

The nitrogen atom requires 3 electrons to complete its octet, which can form a triple bond with another nitrogen atom (they form a covalent bond of the apolar type, where you share 3 pairs of electrons and both elements have equal electronegativity)

Option( D)

A triple bond, because they overlap orbitals to share three pair of electrons

Explanation:

Nitrogen as we know have 5 valence electrons (atomic number=7), hence to make a  noble gas with stable configuration we have provide it with 3 electrons. Furthermore, a covalent bond is formed when two similar atoms of non metals combine with each other to sustain into a molecule hence a total of 3 electrons are shared from each of the nitrogen atom making it chemically stable.

Since nitrogen atom combines with other nitrogen atom sharing 3 electrons each from the atom thus a triple covalent bond formed by the overlapping of electrons.
