To determine: Whether all atoms of an element have the same atomic number.
Concept introduction: An atom is the basic unit of the matter that has the properties of a chemical element. Atom is made up of subatomic particles (neutrons, protons, and electrons). The substance that is made from one type of atom is called as an element. Every element has a unique chemical symbol, atomic number, and atomic mass.
