Matter is made up of extremely small indivisible and indestructible ultimate particles called atoms. Atoms of the same element are identical in all respects i.e. in shape, size, mass and chemical properties. Atoms of different elements are different in all respects and have different masses and chemical properties. Atom is the smallest unit that takes part in chemical combinations.
