The names of CuI, Cr 2 O 3 , Fe(OH) 2, SnBr 4 , BaCl 2 are to be written. Concept introduction: Ionic compounds are made up of ions that are held together by ionic bonding. These ionic compounds are neutral but consist of both positive and negative ions. In nature, many compounds are found as polyatomic ions (poly = many). In general, formulas of ionic compounds depict the ratio of positive and negative ions found in a substance. Moreover, the formulas of compounds are made up of lowest whole number ratio of ions i.e., formula unit. Notably, the number of positive units and the number of negative units will be equal in a chemical formula. The polyatomic ion when used in more than once, parentheses is used, and the parentheses is applied only for polyatomic ions. Ionic compounds having more than one ionic charge, the compound name should have the charge of the metal example: iron(III) chloride.
