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: -The smallest particle of an element is an atom whereas the smallest particle of a compound is a molecule.
Detailed explanation-3: -The smallest atom? If by “biggest” and “smallest", you mean mass (which is a measure of how much matter is there), then the smallest is the hydrogen atom with one proton and one electron.
Detailed explanation-4: -Hence, Helium is the smallest element.
Detailed explanation-5: -An atom is the part of an element. A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons and neutrons. Elements can combine with each other to form molecules via chemical reaction.
