Many ions, particulary anions, are polyatomic. The atoms in these ions are held together by

A

electrovalent bonds

B

hydrogen bonds

C

covalent bonds

D

metallic bonds

Text Solution

Verified by Experts

The correct Answer is:

C

The example of polyatomic anions mainly include oxoaonins obtained from the molecules of oxoacids such as carbonic acid `(H_2CO_3)`, sulphuric acid `(H_2SO_4)`, and phosphoric acid `(H_3PO_4)`. They are carbonate ion `(CO_3^(2-))`, nitrate ion `(NO_3^(-))`, sulphate ion `(SO_4^(2-))`, and phosphate ion `(PO_4^(2-))`, respectively.
