Detailed explanation-1: -An atom is the basic unit of a chemical element. Atoms are made out of three main parts: protons, neutrons and electrons. Protons and neutrons are contained inside the very center of the atom, which is called the nucleus. Electrons orbit around the outside of the nucleus.
Detailed explanation-2: -The basic unit of all matter is the atom. The atom is the smallest unit of matter that can’t be divided using any chemical means and the building block that has unique properties. In other words, an atom of each element is different from an atom of any other element.
Detailed explanation-3: -Given that these particles make up atoms, they are often referred to as subatomic particles. There are three subatomic particles: protons, neutrons and electrons.
