Other Experimental
STRONG OXIDIZING AGENT;Heat of fusion 2290 cal/g mole; 8.6 cal/g;206 °C (solidifies to a glass-like solid);Exists in two oxidation states, /thallous/ (Tl(I)) and /thallic/ (Tl(III)). /Thallium/;In reducing environments, thallous may precipitate as a sulfide; otherwise, it will remain in solution. /Thallium/;... Thallium(I), forms relatively few complexes with the exception of those with halogen, oxygen, and sulfur ligands. In this & several other respects, thallium(I) has chemical properties similar to those of the alkali metal cations. /Thallium (I)/
