All substances present in the Universe are made up of atoms and every single matter – solid, liquid, gas, and plasma is composed of neutral atoms. An atom can be defined as the smallest fundamental unit of the matter which includes all the chemical properties of an element. Atoms are very small particles and its size ranges from 0.1 to 0.5 nanometres. A group of atoms bonded together forms a molecule. An atom is composed of a nucleus consisting of neutrons and protons. This nucleus is bounded by electrons and is always positively charged. Both electrons and protons are oppositely charged particles whereas neutrons have no charge, they are neutral.
