Question

The atoms of an element combine with atoms of another element in small whole number ratio to form molecules of .

Answer 1

1. According to Dalton's atomic theory, the atoms of different elements combine in a simple whole number ratio to form molecules of a compound.
2. For example, Carbon (C) and Oxygen (O) combine in the ratio of 1:2 to form a molecule of the compound Carbon dioxide ( CO₂).

Hence the atoms of an element combine with atoms of another element in a small whole-number ratio to form molecules of the compound.
