검증된 단계별 안내1
Identify the elements in the compound: Ba and Cl. Ba is barium, a metal, and Cl is chlorine, a nonmetal.
Recognize that this is an ionic compound formed between a metal (barium) and a nonmetal (chlorine).
Determine the charges of the ions: Barium typically forms a +2 charge (Ba^{2+}), and chloride ions have a -1 charge (Cl^{-}).
Since the formula is BaCl_{2}, it means two chloride ions balance one barium ion, confirming the charges.
Name the compound by stating the metal name first (barium) followed by the nonmetal with the suffix '-ide' (chloride), resulting in 'barium chloride'.
