ElementAntimony
SymbolSb
Atomic Mass121.75
Atomic Number51
Name OriginsGreek, anti + monos = not alone, Latin, stibium
Year DiscoveredPrehistoric
Discovered CreditsProbably known to the ancients and certainly to the alchemists.
RemarksMetalloid element with various allotropes, of which metal is bright, silvery, hard, and brittle. Stable in dry air and not attacked by dilute acids of alkalis. Used to harden other metals, in storage batteries, bearings, etc.
Diagnostic TestsAntimony is usually detected by the coating of oxide formed by roasting on charcoal or the open tube.Antimonides, antimony, etc. (As2-): A sample of the powdered mineral gives off a dense sublimate of Sb2O3 when roasted on charcoal without the arsenic odor. In the open tube test, they give a white, volatile, crystalline sublimate of Sb2O3 at a much higher temperature than arsenic. In the closed tube test with sulfur, they yield a black sublimate when hot and red or reddish brown when cold. Antimonates (SbO4): can be detected by lack of a garlic odor (arsenic) and the white sublimate yielded when a mixture of the powdered mineral with charcoal dust and Na2CO3 is heated with a reducing flame on a charcoal block. The pale green flame test for Antimony is not very decisive.
