Interpretation:
The formulas for the given compounds are to be written.
Concept Introduction:
An ionic compound is one that consists of ions with electrostatic interactions between them, which is termed as ionic bonding.
The
Stock system is the method for naming the metal ions that have more than one oxidation state in compounds, indicated by Roman numeral in parenthesis just after the name of the metal ion.
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.
