Question

Atoms of certain elements combine to form molecules of that element.

• A. True
• B. False

Answer 1

The correct option is A True

Molecules are the smallest units of matter that can exist independently. Two or more atoms combine in simple whole number ratio to form molecules.

Based on the type of atoms present in a molecule, molecules can be two types

1.molecules of elements

2.Molecules of compounds

Molecules of elements

Atoms of certain elements combine to form molecules of those elements. Example- molecule of oxygen(${\mathrm{O}}_2$),molecules of hydrogen(${\mathrm{H}}_2$).

Molecules of compounds

The molecules of certain substances are made up of two or more types of atoms. Example- molecule of water(${\mathrm{H}}_2\mathrm{O}$), molecule of carbon dioxide (${\mathrm{CO}}_2$).

Therefore the given statement is true ie, atoms of certain elements combine to form molecules of that element.
