Answer 2

Answer:

The smallest tiny particles of matter which can't be divided further is called atom, i.e., an atom is the smallest building block of matter. For example: Sodium (Na), Hydrogen (H), Oxygen (O), etc

A group of two or more than two atoms of the same or different elements that are chemically bonded together is called a molecule. For example: Two atoms of hydrogen (H2) and one atom of oxygen (O2) react with each other and form one molecule of water.
