Question

Define the following: Chemical bond.

Answer 1

• The attractive forces between atoms, molecules or ions to form compounds is called a chemical bond. It involves either the transfer or sharing of electrons between different atoms, ions or molecules.
• Chemical bond is of two types: Ionic bond and Covalent bond.
• Ionic bond is formed by the transfer of electrons while covalent bond is formed by the sharing of electrons between the atoms, ions or molecules.
• Examples: In Sodium chloride (NaCl), there is a bond formed between Sodium ion (Na⁺) and Chloride ion (Cl^-) by the transfer of electron.
