This is a diagram that explains AZE notation. On the left is a model of an atom, with a nucleus in the middle consisting of two circular protons marked with a "+" symbol tightly placed next to two blue neutrons. A ring surrounds the nucleus, containing two circular electrons that are smaller than the neutrons and the electrons. A description for protons says in a neutral atom they are the same as the number of electrons. On the right is the AZE notation of Helium, with the chemical symbol He with a superscript and subscript to the left of the symbol. The superscript, 4, is the atomic / mass number, the sum of the protons and neutrons. The subscript, 2, is the number of protons.

Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3; it is usually shown at the foot of the table to save horizontal space.
