The incorrect formulas are to be determined and their correct forms are to be written. Concept Information: The element symbols and subscripts in an ionic compound are represented by the help of a chemical formula. Electrical neutrality is maintained in all the chemical compounds, due to which the ions present in an ionic compound have a fixed ratio in such a way that the positive charge is equal to the negative charge. 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.
