When nitrogen and magnesium form an ionic bond, what is the formula? (2 points) select one: a. n3mg2 b. n2mg3 c. mg2n3 d. mg3n2

Answer is: d. Mg3N2.

Mg₃N₂ is magnesium nitride.

Nitrogen (nonmetal) in this chemical compound has oxidation number -3 and magnesium (metal) has oxidation number +2.

Smallest common multiple for 3 and 2 is 6.

number of nitrogen atoms = 6 ÷ 3.

number of nitrogen atoms = 2, there are two nitrogen atoms.

number of magnesium atoms: 6 ÷ 2.

number of magnesium atoms = 3.

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
