In chemistry, it is the miniature piece of an element that can participate in any chemical reaction but can not remain in an independent state. According to the great sage Kanad of India, all matter is made up of very fine microwaves, which are called atoms. Atoms are made up of protons, neutrons, and electrons. The size of atoms is minimal and the mass is very small. Hydrogen is the smallest and lightest among atoms. Its radius is a barber of 0.3 x 10–10 m. The chemical properties of a substance are the tendency to form compounds by combining atoms of a substance with the same or atoms of another substance. A molecule by chance has no such tendency. The chemical properties of a substance are atoms. As a result of modern discoveries in the 20th century, JJ Scientists such as Thomson, Rutherford, Chadwick, etc. proved that the atom is divisible and mainly consists of three basic particles, called electrons, protons and neutrons.
