Question

When one atom of Sodium combines with one atom of Chlorine, a molecule of Sodium chloride is formed.

• A. True
• B. False

Answer 1

The correct option is A True

Molecule: A molecule is the smallest particle of a compound that can exist independently and have its properties.

• The valency of Sodium$\left(\mathrm{Na}\right)$ atom is 1 and Chlorine$\left(\mathrm{Cl}\right)$ atom is 1. Therefore, one Na atom combine with one Cl atom to form Sodium chloride $\left(\mathrm{NaCl}\right)$ compound.
• It is made up of combining two different atoms in a whole number ratio.

Thus, the given statement is True. i.e., When one atom of Sodium combines with one atom of Chlorine, a molecule of Sodium chloride is formed.
