검증된 단계별 안내1
Identify the elements in the compound RbCl. Rb is the symbol for rubidium, and Cl is the symbol for chlorine.
Determine the type of compound. Since Rb is a metal (an alkali metal) and Cl is a nonmetal, the compound is ionic.
Name the cation (positive ion) first. The cation is rubidium, so use the element name 'rubidium' directly.
Name the anion (negative ion) second. For chlorine as an anion, change the ending to '-ide', resulting in 'chloride'.
Combine the names of the cation and anion to get the full name: 'rubidium chloride'.
