The number of elementary positive charges (protons) contained within the nucleus of an atom. It is denoted by the letterZ. Correspondingly, it is also the number of planetary electrons in the neutral atom. The concept of atomic number emerged from the work of G. Moseley, done in 1913–191...
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...
an element and are a count of the protons and neutrons found in that isotope's nucleus. Interestingly, the number of protons will remain constant, regardless of the isotope, but the number of neutrons will change. This is because an atom's element is identified by the number of protons. ...
