thallium
n 1: a soft grey malleable metallic element that resembles tin
but discolors on exposure to air; it is highly toxic and is
used in rodent and insect poisons; occurs in zinc blende
and some iron ores [synonym: {thallium}, {Tl}, {atomic number
81}]

Thallium \Thal"li*um\, n. [NL., fr. Gr. ? young or green shoot
or branch, twig. So called from a characteristic bright green
line in its spectrum.] (Chem.)
A rare metallic element of the aluminium group found in some
minerals, as certain pyrites, and also in the lead-chamber
deposit in the manufacture of sulphuric acid. It is isolated
as a heavy, soft, bluish white metal, easily oxidized in
moist air, but preserved by keeping under water. Symbol Tl.
Atomic weight 203.7.
[1913 Webster]
