Detailed explanation-1: -An Atom is the smallest unit of matter (Anything that has mass and occupies some space). every state (solid, liquid, gas, and plasma) is composed of neutral or ionised atoms. Every atom is composed of a nucleus and that nucleus consists of charge particle protons and neutral particles neutrons.

Detailed explanation-2: -An atom is the basic building block of chemistry. It is the smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element.

Detailed explanation-3: -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-4: -Reason: Molecule is the smallest particle of matter that exists independently and is formed by the combination of atoms.

Detailed explanation-5: -British chemist John Dalton proposed the basic idea of the nature of matter. Dalton took the name ‘atoms’ as given by the Greeks and said that the smallest particles of matter are atoms. The size of an atom is extremely small, much smaller than our imagination. More items
