Neodynium

Element Name: Neodynium

Element Symbol: Nd

Atomic Mass: 144

Atomic Number: 60

Protons:60

Electrons: 60

Discovery (who & when): Von Welsbach, 1885

How It Was Named: Von Welsbach sperated an elemnt called didymium, into two new elemental components called Praseodymia and Neodymia. After repeated seperation of ammumium didymium nitrate.

State of Matter: Solid (metal)

Melting Point: 1021°C

Boiling Point: 3074°C

Characteristics:Neodynium is a bright, silvery, matellic laster. One of the more reactive rare-earth metals and tarnishes in the air quickly. It forms oxide that spalls off and exposes metal oxidation. Neodynium exists in two allotropic forms, with a double hexagonal to a body-center cubic structure taking place at 863°C.

Uses of Elements: Neodynium is used for coloring welders goggles. Astronomical work to produce sharp bands by which spectral lines may be calibrated. Glass containing Neodynium can be used as a laser material to produce coherent light. Neodynium salts are also used as colorent for enamel.

Interesting Facts:
 * The metal cost is $1/g.
 * Neodynium has a low acute toxic rating.
 * Natural Neodynium has seveb stable isotopes.
