This is the chemical formula of Nitrogen gas. N₂

Which of the following is NOT true of nitrogen gas?

A. It is made of two atoms.

B. It is a molecule.

C. It is an element.

D. It is a compound.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
