What is the chemical formula of the ionic compound produced through interaction of each of the following pairs of elements?
- a. Li and S
- b. Mg and N
- c. Ca and Cl
- d. K and F
(a)
Interpretation:
The chemical formula for the ionic compound produced through interaction
Concept Introduction:
Ions are formed by 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.
