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.
Gallium in medical degree.
