Atomic number: The number of protons in an atom. Each element is uniquely defined by its atomic number.

Atomic mass: The mass of an atom is primarily determined by the number of protons and neutrons in its nucleus. Atomic mass is measured in Atomic Mass Units (amu), which are scaled relative to carbon, 12C, that is taken as a standard element with an atomic mass of 12. This isotope of carbon has 6 protons and 6 neutrons. Thus, each proton and neutron has a mass of about 1 amu.

Isotope: Atoms of the same element with the same atomic number, but a different number of neutrons. The isotope of an element is defined by the sum of the number of protons and neutrons in its nucleus. Elements have more than one isotope with varying numbers of neutrons. For example, the two common isotopes of carbon, 12C and 13C, have 6 and 7 neutrons, respectively. The abundance of each isotope depends on the source of materials. For relative abundances of isotopes in nature, see reference on Atomic Weights and Isotopic Compositions.

Atomic weight: Atomic weight values represent weighted average of the masses of all naturally occurring isotopes of an element. The values shown here are based on the IUPAC Commission determinations based on the 2021 Table: https://iupac.qmul.ac.uk/AtWt/.
Reference: Standard atomic weights of the elements 2021 (IUPAC Technical Report)

The elements marked with an asterisk have no stable nuclides. For these elements, the weight value represents the mass number of the longest-lived isotope of the element.

Electron configuration: See next page for explanation of electron configuration of atoms.
