Read each question carefully and provide the best answer. Remember the rules for naming binary ionic compounds.
Binary ionic compounds are formed between a metal and a nonmetal. The metal always comes first in the name and formula, followed by the nonmetal. The nonmetal's name changes its ending to '-ide'. For transition metals, a Roman numeral is used to indicate its charge.
