(a)
Interpretation:
To write the chemical formula for an ionic compound formed from the following ions-
Concept Introduction:
Ions are formed by the loss or gain of electrons. The formation of ion requires the presence of two elements, these two elements are: one is metal atom and another one is non-metal atom. Metal atom loses electron and non-metal atom accepts electron.
The ratio in which positive and negative ions combine is the ratio which achieves charge neutrality for the resulting compound.
There three rules to remember while writing the chemical formulas. They are as follows:
- First write the symbol for positive ion.
- The charges of the ions are not shown in the formula.
- The numbers in the formula give the combining ratio for the ions.
