Detailed explanation-1: -An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton’s Atomic Theory : 1. All matter is composed of atoms, and atoms are indivisible and indestructible.

Detailed explanation-2: -Atoms are the smallest units of matter that have all the characteristics of an element. Atoms combine to form molecules. Atoms are composed of smaller particles known as protons, neutrons, and electrons.

Detailed explanation-3: -Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

Detailed explanation-4: -Molecules make up everything around us and they are very, very small. But those molecules are made of atoms, which are even smaller. And then those atoms are made up of protons, neutrons and electrons, which are even smaller.

Detailed explanation-5: -Electron: Electrons are negatively charged particles that revolve around the nucleus. Proton: Protons are the positively charged particles present in the nucleus. Neutrons: Neutrons are the neutral particles present in the nucleus along with protons.
