My Story: I was discovered in 1875 by a man named Paul Emile Lecoq de Boisbaudran. My name is from the Latin root, Gallia. I came from bauxite, germanite, and coal.

Paul Emile Lecoq de Boisbaudran biography
Gallium was discovered spectroscopically by Paul-Emile Lecoq de Boisbaudran. He obtained the free metal by electrolysis of a solution of the hydroxide Ga(OH)3 in KOH.



My Jobs: I am used for creating solidstate devices like transistors. My other form, Gallium arsenide, converts electricity into coherent light. 90 tons of gallium (2 or 3 years of world production) is used to detect solar neutrinos.
Gallium - Chemistry with Mr. Olson
Gallium is used as type of nuclear scan, involving galliu, to determine wheter the person has inflammation in the lungs. Gallium is injected into a vein and then x-rays are taken to see if gallium has built up, or accumulated, in the lungs. This test is to see if there is sarcoidosis, or inflammation in the lungs.
