The correct formulas of the given compounds are to be given. Concept Introduction: When metals react with non-metals ionic compounds are formed. The element symbols and subscripts in an ionic compound are represented by the help of a chemical formula. Ionic compound is a compound consisting of ions having electrostatic interaction between them which is termed as ionic bonding. Rules for writing formula for ionic compounds: The cation is given first in the formula. In the formula the subscripts must produce an electrically neutral formula unit. The subscripts must be the smallest set of whole numbers possible. The finished formula for substance does not include the charges on the ions. When a subscript is 1 it is left off, no subscript implies as subscript of 1.
