Experimental Properties:Diatomic in vapor state; atomic number 52, valence 2, 4, 6; in air dissolves in potassium hydroxide; electrical resistivity at 19.6 °C: 200,000 micro-ohms/cm; reacts with nitric acid, not with hydrochloric acid; linear coefficient of thermal expansion: 16.8X10-6/deg C; latent heat of fusion: 4.27 kcal/mol; hardness (Mohs): 2.3; magnetic susceptibility at 18 °C: -0.31X10-6 cgs; specific heat (solid): 0.047 cal/g/deg C|Combines with halogens, does not react with sulfur or selenium; modulus of elasticity: 6000000 psi. ... Eight stable isotopes: 120, 122, 123, 124, 125, 126, 128, 130; reacts with concentrated or fuming sulfuric acid
Air and Water Reactions:A finely divided suspension of elemental tellurium in air will explode. Insoluble in water.
Reactive Group:Metals, Less Reactive
Reactivity Alerts:Pyrophoric
Reactivity Profile:TELLURIUM is attacked by chlorine fluoride with incandescence. When tellurium and potassium are warmed in an atmosphere of hydrogen, combination occurs with incandescence [Mellor 11:40. 1946-47]. Burning tellurium produces toxic tellurium oxide gas. Avoid solid sodium, halogens, interhalogens, metals, hexalithium disilicide. Reacts with nitric acid; reacts with concentrated sulfuric acid forming a red solution. Dissolves in potassium hydroxide in the presence of air with formation of deep red solution; combines with halogens. Avoid antimony and chlorine trifluoride; chlorine trifluoride reacts vigorously with tellurium producing flame. Fluorine and tellurium react with incandescence. Lithium silicide attacks tellurium with incandescence. Reaction with zinc is accompanied by incandescence (same potential with cadmium, only hazard is less). A vigorous reaction results when liquid tellurium is poured over solid sodium [EPA, 1998].
