All of the halogens tend to form salts, compounds — formed, along with water, from the reaction of an acid and base — that bring together a metal and a nonmetal. Due to this tendency, the first of the family to be isolated — chlorine, in 1811 — was originally named "halogen," a coination of the Greek words halos, or salt, and gennan, "to form or generate."

Oxide - Nonmetal oxides | Britannica

Oxide - Oxide - Nonmetal oxides: All nonmetals form covalent oxides with oxygen, which react with water to form acids or with bases to form salts. Most nonmetal oxides are acidic and form oxyacids, which in turn yield hydronium ions (H3O+) in aqueous solution. There are two general statements that describe the behaviour of acidic oxides. First, oxides such as sulfur trioxide (SO3) and
