Question

lonic bond is formed due to which of the following?

• A. Transfer of electrons from one atom to another atom
• B. Electrostatic attraction between two oppositely charged ions
• C. Sharing of electrons between two atoms
• D. Both (1) and (2)

Answer 1

The Correct Option is D

Correct answer: Both (1) and (2)
 
Explanation:
An ionic bond is formed by:
1. Transfer of electrons from one atom (usually a metal) to another atom (usually a non-metal).
2. The resulting ions (a positively charged cation and a negatively charged anion) are then held together by the electrostatic force of attraction. 
For example, in sodium chloride (NaCl):
Sodium donates one electron to chlorine → Na⁺ and Cl⁻
These oppositely charged ions are attracted to each other forming an ionic bond. 

Therefore, both transfer of electrons and electrostatic attraction are involved.
