What are some classic textbooks or scientific articles that discuss atomic number?

Isotopes are atoms of the same element that have the same number of protons (ie, atomic number, "Z") but a different number of neutrons. An atom consists of a nucleus containing protons and neutrons, surrounded by electrons. is called its atomic number. a heavy brittle metallic element of the platinum group; used in alloys; occurs in natural alloys with platinum or osmium. Each atom, therefore, can be assigned both an atomic number (the number of protons equals the number of electrons) and an atomic weight (approximately equaling ...
