Neodymium (Nd)

By: Evan Martin

Fun Facts

Neodymium is the 60th element on the periodic table. It is twice as common as lead but half as common as copper. Neodymium is normally a solid on Earth.

Properties

Neodymium has an atomic mass of 144.24 and has 60 protons and electrons. With a melting point of 1021 Celsius and a boiling point of 3100 Celsius, Neodymium is a solid at room temperature. It has a density of 7.010g/cc. Neodymium is gray/silvery and is very conductive and fairly malleable. As far as chemical properties go, Neodymium rapidly tarnishes when exposed to air, and Neodymium powder is flammable.

History

Neodymium was first discovered in 1885 in Vienna. It was first discovered by Carl Auer Von Welsbach. It was discovered when another material, Didymium, was separated into 2 elements. Bohuslav Brauner attempted to separate Didymium in 1882, but he failed to complete his experiment.

Magnetics

The most common use of Neodymium is in permanent magnets. These magnets are incredibly strong and have many uses, but can be very dangerous because of the force that the magnets can exert.

Isotopes

Neodymium has quite a few isotopes. There are 7 standard isotopes, and a total of 31 different radioactive isotopes. One of the isotopes is Nd150. This isotope is used in paints and acrylics.

Compounds

Neodymium is used as a component in Misch metal, which is a metal used in light flints, such as in a lighter.
