Question

which of the following is an example of an ionic compound? view available hint(s) water oxygen carbon dioxide sodium chloride

Explanation:

Ionic compounds are formed by the transfer of electrons from a metal to a non - metal. Sodium chloride (\(NaCl\)) is formed by the transfer of an electron from sodium (a metal) to chlorine (a non - metal). Water (\(H_2O\)) is a covalent compound formed by the sharing of electrons between hydrogen and oxygen. Oxygen (\(O_2\)) is a diatomic molecule (a non - ionic substance as it is composed of only non - metal atoms sharing electrons). Carbon dioxide (\(CO_2\)) is also a covalent compound formed by the sharing of electrons between carbon and oxygen.

Answer:

sodium chloride
