Potassium
(gcide) | Potassium \Po*tas"si*um\, n. [NL. See Potassa, Potash.]
(Chem.)
An Alkali element, occurring abundantly but always combined,
as in the chloride, sulphate, carbonate, or silicate, in the
minerals sylvite, kainite, orthoclase, muscovite, etc. Atomic
weight 39.0. Symbol K (Kalium).
[1913 Webster]
Note: It is reduced from the carbonate as a soft white metal,
lighter than water, which oxidizes with the greatest
readiness, and, to be preserved, must be kept under
liquid hydrocarbons, as naphtha or kerosene. Its
compounds are very important, being used in glass
making, soap making, in fertilizers, and in many drugs
and chemicals.

Potassium permanganate, the salt KMnO4, crystallizing in
dark red prisms having a greenish surface color, and
dissolving in water with a beautiful purple red color; --

1. A lizardlike reptile of the genus Cham[ae]leo, of
several species, found in Africa, Asia, and Europe. The
skin is covered with fine granulations; it has eyes which
can move separately, the tail is prehensile, and the body

to blend with its surroundings. [Also sometimes spelled

objects about it, or with its temper when disturbed. In

admitting the light, it changes to brown, bottle-green,
or blood red, of various shades, and more or less
mottled in arrangment. The American chameleons belong
