question 29 of 50
what happens when two nitrogen atoms share electrons?
a. they form a water molecule.
b. they form an ionic bond.
c. they form an oxygen molecule.
d. they form a covalent bond.

Explanation:

When atoms share electrons, it's a covalent bond. Nitrogen atoms share electrons (each nitrogen has 5 valence electrons and needs 3 more to complete the octet, so they share 3 pairs of electrons). An ionic bond is when electrons are transferred (not shared). A water molecule ($H_2O$) has hydrogen and oxygen. An oxygen molecule ($O_2$) has oxygen atoms. So the correct answer is that two nitrogen atoms sharing electrons form a covalent bond.

Answer:

D. They form a covalent bond
