What is an ionic bond ? With two suitable examples, explain the diference between an ionic and a covalent bond ?

Explanation

### Step-by-Step Solution

**Step 1: Define Ionic Bond**
An ionic bond is a type of chemical bond that is formed through the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions). This bond is created when one atom transfers one or more electrons to another atom, resulting in the formation of charged ions.

**Step 2: Explain the Formation of Ionic Bonds**
Ionic bonds are formed when there is a significant difference in electronegativity between the two atoms involved. The atom with a higher electronegativity will attract the electron(s) from the other atom, leading to the formation of cations and anions. The electrostatic force of attraction between these oppositely charged ions holds them together.
