Question

Select the correct statement(s) regarding ionic bond:

• A. It involves transfer of electrons between atoms
• B. It involves formation of positive and negative ions
• C. It involves sharing of electrons between atoms
• D. It is usually formed between a metal and a non-metal

Answer 1

Answer: (A), (B), (D)

The correct options are
A

It involves transfer of electrons between atoms

B

It involves formation of positive and negative ions

D

It is usually formed between a metal and a non-metal

Elements try to become stable by attaining an inert gas configuration. In this process, they either lose or gain electrons or share electron pairs. Atoms form positive ions when they lose electrons and they form negative ions as they gain electrons. Electron transfer takes place while forming ions and it happens in an ionic bonding. A metal and a non-metal combine to form an ionic compound by complete transfer of electrons from a metal to a non-metal. A covalent bond, on the other hand, involves sharing of electron pairs.
