Interpretation: The method for writing the chemical formula of binary ionic compounds from their names is to be stated.
Concept Introduction: In a binary ionic compound, the name of the cation is written first followed by the name of the anion. The total charge of cations is equal to that of the anions, hence the compound is overall neutral.
Answer to Problem 63A
To write the chemical formula of binary ionic compounds write the
Explanation of Solution
Write the symbol and charge of the cation first and that of the anion second. Then the magnitude of charges is interchanged to become the subscript to ensure electrical neutrality. E.g.
