Question

16. The formula of a zincate radical is _______.

Answer 1

The formula of a zincate radical is ZnO₂^2-

The compounds are represented with the help of shorthand notations called formulae which are derived from the symbols of the constituent elements.

A group of atoms possessing either positive or negative charge by losing or gaining one or more electrons is called radical.

• Radicals are actually chemical species. These chemical species are of two types- positive and negative radicals.
• The chemical formula of zincate radical is ${{\mathrm{ZnO}}_2}^{2-}$.
• Here, zincate radical is an example of a negative radical. Its valency as a whole is 2.

Therefore, the formula of a zincate radical is ZnO₂^2-
