From       : Greek anti+monos, "not along"; suggests that the metal is not
             found along in nature; the symbol is taken from the name of
             mineral stibnite, the most common natural source of antimony.

[Properties]

  Antimony is a silvery-white crystalline substance that has a metallic
luster. It is brittle, yet soft - that is, it fractures readily into small
pieces, yet scratches easily, too. This element is in the oxygen group,
Group VIA, on the periodic chart.
  Physically, antimony behaves more like a nonmetal such as sulfur. It is
a poor conductor of heat and electricity, and it flakes and crumbles easily.
Chemically, antimony resembles a metal. It alloys readily with most metals,
it is found in nature in the company of other metals such as lead and
silver, and it behaves ionically like a metal.
  There are two allotropic forms of antimony: the normal metallic form and
an amorphous gray form. Older texts refer to explosive and yellow forms as
well, but these have been shown to be compounds rather than two additional
allotropes of the element.
