Answer

a. Dinitrogen Monoxide b. Copper(I) Oxide c. Lithium Oxide

Work Step by Step

a. Nitrogen and Oxygen are both nonmetals. Therefore, $N_2O$ is a covalent compound with two nitrogens and one oxygen. Therefore, the formula is Dinitrogen Monoxide. b. Copper is a metal and does not have a constant ionic charge. Oxygen is a nonmetal and has a constant ionic charge of 2-. Therefore, if we were to bond two coppers with one oxygen, one copper ion would have a charge of 1+. Therefore, the ionic compound's name is Copper(I) Oxide. c. Lithium is a metal and has a constant ionic charge. Oxygen is a nonmetal and contains a constant ionic charge. Therefore, $Li_2O$ is an ionic compound and is called Lithium Oxide.
