This website was made Gabriela Strachman and Mohammed Raeissi, this website is a chemistry project about groups of elements of the period table. Unfortunately word press automatically changes the order of the pages depending on the alphabetic order; the order of the groups are:
Alkali Metals, Alkaline Earth Metals, Rare Earth Metals, Transition Metals, Other Metals, Nonmetals, Halogens, and Noble Gases.
The Bibliography is separated into 2 groups, the first group has the sources of Alkaline Earth Metals, Transition Metals, Nonmetals, and Noble Gases. The second group has the sources of Alkali Metals, Rare Metals, Other Metals and Halogens.
