DescriptionECHEMI Editorial Referencesilver-grey metal, tarnishing quickly in air Thallium is a soft, bluish-white, heavy, very soft metal insoluble in water and organic solvents. It turns gray on exposure to air.
Thallium appears as bluish-white soft malleable metal or gray granules. Density 11.85 g / cm3. Emits toxic fumes when heated. May be packaged under water.|BLUISH-WHITE VERY SOFT METAL. TURNS GREY ON EXPOSURE TO AIR.|Light-gray to tan powder with a slightly aromatic odor.|Bluish-white metal that turns gray on exposure to air.
Thallium appears as bluish-white soft malleable metal or gray granules. Density 11.85 g / cm3. Emits toxic fumes when heated. May be packaged under water.|Pure thallium is a bluish-white metal that is found in trace amounts in the earth's crust. In the past, thallium was obtained as a by-product from smelting other metals; however, it has not been produced in the United States since 1984. Currently, all the thallium is obtained from imports and from thallium reserves..In its pure form, thallium is odorless and tasteless. It can also be found combined with other substances such as bromine, chlorine, fluorine, and iodine. When it's combined, it appears colorless-to-white or yellow..Thallium is used mostly in manufacturing electronic devices, switches, and closures, primarily for the semiconductor industry. It also has limited use in the manufacture of special glass and for certain medical procedures.|Thallium is a metallic element first identified and named from the brilliant green line in its flame spectrum (from Greek thetaalphalambdalambdaomicronsigma, a green shoot).|A heavy, bluish white metal, atomic number 81, atomic weight [204.382; 204.385], symbol Tl.Basic Info-

Appearance:Clear colorless rod
Density:11.8 g/cm3
Melting Point:304 °C
Boiling Point:1473 °C
Flash Point:420°F
Water Solubility:Solubility in water: none
Storage Conditions:In the presence of water, a hydroxide is formed. Thallium is therefore stored under petroleum spirit, glycerine, or deaerated water. On prolonged storage under water with free access of air, metallic thallium becomes covered with large crystals of thallium(I) carbonate, and the water becomes saturated with this salt. To protect against oxidation, rods of thallium are coated with paraffin.

Air and Water Reactions:Flammable in the form of powder or dust. Insoluble in water.
Reactive Group:Metals, Less Reactive
Reactivity Alerts:Strong Reducing Agent
Reactivity Profile:THALLIUM is a reducing agent. Reacts so vigorously with fluorine that the metal becomes incandescent [Mellor 5:421 1946-47].
Physical Dangers:Dust explosion possible if in powder or granular form, mixed with air.
Heat of Vaporization:795 kJ/mol
