GENERAL KNOWLEDGE

Detailed explanation-1: -All the matter or material that we see around us, and even the things which we cannot see through our naked eyes like bacteria, air etc are all made up of atoms collectively. Although atoms are made up of sub-atomic particles mainly including electrons, protons and neutrons.

Detailed explanation-2: -Dalton’s atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.

Detailed explanation-3: -Things that are matter include stars, air, water, tables, chairs, trees, your body, your brain, and pretty much everything that you see around you. All of these things are made up of molecules – but molecules aren’t the smallest pieces of matter, because every molecule is made up of even smaller pieces called atoms.
