mo·lyb·de·num

 (mə-lĭb′də-nəm)
n. Symbol Mo
A hard, silvery-white metallic element used to toughen steels and in corrosion-resistant nickel alloys. An essential trace element in plant nutrition, it is used in fertilizers, dyes, enamels, and reagents. Atomic number 42; atomic weight 95.96; melting point 2,623°C; boiling point 4,639°C; specific gravity 10.22 (at 20°C); valence 2, 3, 4, 5, 6. See Periodic Table.

[New Latin, from earlier molybdena, lead ore, from Latin molybdaena, galena, from Greek molubdaina, from molubdos, lead, probably from Lydian mariwda, dark.]
