Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, [13] gallium is in group 13 of the periodic table and is similar to the other metals of the group (aluminium, indium, and thallium). Elemental gallium is a relatively soft, silvery metal at standard temperature and pressure. In its liquid state, it becomes silvery white.
Gallium was discovered by French scientist Paul-Émile Lecoq de Boisbaudran, who named it in honor of France ("Gallia" in Latin); allegations were later made that he had also named it for himself, as "gallus" is Latin for "le coq", but he denied that this had been his intention. [8]
Perey discovered it as a decay product of 227 Ac. [177] Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well.

From 1809 onward, light metals, such as magnesium, aluminium, and titanium, were discovered, as well as less well-known heavy metals including gallium, thallium, and hafnium. Some heavy metals are either essential nutrients (typically iron, cobalt , copper and zinc ), or relatively harmless (such as ruthenium , silver and indium ), but can be ...
