Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun A bright white, soft, ductile metallic element found in several minerals, notably vanadinite and carnotite, having good structural strength and used in rust-resistant high-speed tools, as a carbon stabilizer in some steels, as a titanium-steel bonding agent, and as a catalyst. Atomic number 23; atomic weight 50.942; melting point 1,910°C; boiling point 3,407°C; specific gravity 6.0 (18.7°C); valence 2, 3, 4, 5. cross-reference: Periodic Table.
from The Century Dictionary.
- noun Metallic vanadium in a compact state has been obtained by fusion in an electric furnace. It has a gray color, is lustrous, and, as thus far observed, brittle, though perhaps this may be due to impurity of the metal; it is with difficulty freed from oxygen, carbon, and nitrogen.
- noun Chemical symbol, V; atomic weight, 51.2. A metal first discovered by Del Rio, in 1801, in a lead ore from Mexico, and called by him erythronium, because its salts became red when heated with acids.

- noun (Chem.) A rare element of the nitrogen-phosphorus group, found combined, in vanadates, in certain minerals, and reduced as an infusible, grayish-white metallic powder. It is intermediate between the metals and the non-metals, having both basic and acid properties. Symbol V (or Vd, rarely). Atomic weight 50.94 (C12=12.000).

Minerals found in association with uranium, especially vanadium, which is used in hardening steel, sparked the first real rush in the 1930s; uranium for bombs and energy then followed in a stuttering pattern of boom and bust into the 1980s, when the nation's nuclear energy program mostly went into mothballs.
