Gadolinium is a chemical element originated from Johan Gadolin, chemist, physicist and mineralogist. It was first mentioned in 1880 and observed by J. C. G. de Marignac. The isolation was later accomplished and announced by F. L. de Boisbaudran. “Gd” is the canonical chemical symbol of gadolinium. Its atomic number in the periodic table of elements is 64 with location at Period 6 and Group 3, belonging to the f-block. The relative atomic mass of gadolinium is 157.25(3) Dalton, the number in the brackets indicating the uncertainty.
