Information Neodymium is a rare earth loanthanide that reacts with Oxygen to form a pink oxide. It is used to produce very powerful magnets. Joseph's Element Collection Joseph has not yet obtained a sample of Neodymium. References: Holden, Norman E. (March 30, 2004). "History of the origin of the chemical elements and their discoverers."
