Question

Select the incorrect statement regarding ionic compounds.

• A. Formed by transfer of electrons between atoms.
• B. Involves formation of positive and negative ions.
• C. Involves sharing of electrons between atoms.
• D. Formed between a metal and a non-metal.

Answer 1

The correct option is C Involves sharing of electrons between atoms.

Atoms try to become stable by attaining electronic configuration of the nearest noble gas. In this process, they either lose or gain electrons. Atoms form positive ions and negative ions when they lose and gain electrons respectively.

During the formation of an ionic compound, electron transfer takes place leading to the formation of ions.

A metal and a non-metal combine to form an ionic compound by complete transfer of electrons from a metal to a non-metal.
