A chemical series is a group of chemical elements whose physical and chemical characteristics vary progressively from one end of the series to another.

Chemical series were discovered before the creation of the periodic table of the chemical elements, which was created to try to organise the elements according to their chemical properties.

Several chemical series correspond exactly to periodic table groups: this is not a coincidence, the physical properties that group them arise from the same atomic orbital configurations that place them in the same group in the periodic table.

The chemical series of the periodic table are the:
