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.

Write the chemical formulas for (a) potassium sulfide, (b) calcium hydrogen carbonate c) nickel(II) perchlorate. for (d) silicon tetrabromide, (e) disulfur dichloride.
Give the chemical formula for (a) chlorite ion, (b) chlorideion, (c) chlorate ion, (d) perchlorate ion, (e) hypochlorite ion.
Elements in the same group of the periodic table often form oxyanions with the same general formula. The anions are also named in a similar fashion. Based on these observations, suggest a chemical formula or name, as appropriate, for each of the following ions: (a) BrO4 -, (b) SeO3 2-, (c) arsenate ion, (d) hydrogen tellurate ion.
