Atomic Number

Domain	Definition
Aerospace	(Symbol Z) An integer that expresses the positive charge of the nucleus in multiples of the electronic charge e. It is the number of electrons outside the nucleus of a neutral (un-ionized) atom and, according to widely accepted theory, the number of protons in the nucleus. See atomic weight, Table IV. An element of atomic number Z occupies the Zth place in the periodic table of the elements. Its atom has a nucleus with a charge +Ze, which is normally surrounded by Z electrons, each of charge -e.For example, the carbon isotope 6C14 has an atomic number of 6 and an atomic mass of 14.

Specialty Definition: Atomic number

The atomic number (Z) is a term used in chemistry and physics to represent the number of protons found in the nucleus of an atom.

The atomic number originally meant the number of an element's place in the Periodic table. When Mendeleev arranged the known chemical elements grouped by their similarities in chemistry, it was noticeable that placing them in strict order of atomic mass resulted in some mismatches. Iodine and Tellurium, if listed by atomic mass, appeared to be in the wrong order, and would fit better if their places in the table were swapped. Placing them in the order which fit chemical properties most closely, their number in the table was their atomic number. This number appeared to be approximately proportional to the mass of the atom, but, as the mass/chemistry discrepancy showed, reflected some other property than mass.

The anomalies in this sequence were finally explained after research by Henry Gwyn Jeffries Moseley in 1913 with the discovery of atomic structure: the mass being the sum of the protons and neutrons in the atomic nucleus, while the chemical properties derive from the number of electrons in the atom, which matched the number of protons.
