Question

A molecule of oxygen is made up of_____ atoms of the element oxygen.

Answer 1

Molecules are the smallest units of matter that can exist independently. Two or more atoms combine in a 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. 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, the same type of atoms combines combine to form molecules of elements.

Therefore a molecule of oxygen is made up of 2 atoms of the element oxygen.
