What's the difference between caesium and lepidolite?

Caesium


Definition:

  • (n.) A rare alkaline metal found in mineral water; -- so called from the two characteristic blue lines in its spectrum. It was the first element discovered by spectrum analysis, and is the most strongly basic and electro-positive substance known. Symbol Cs. Atomic weight 132.6.

Lepidolite


Definition:

  • (n.) A species of mica, of a lilac or rose-violet color, containing lithia. It usually occurs in masses consisting of small scales. See Mica.
