203Tl Information

Pure, unreacted thallium appears silvery-white and exhibits a metallic lustre. Upon reacting with air, it begins to turn bluish-grey and looks like lead. It is very malleable, and can be cut with a knife. Thallium as 41 isotopes. There are two stable natural isotopes of thallium. Tl-204 being the most stable with a half-life of 3.78 years. Thallium sulphate was used as a rodenticide. Thallium sulphine's conductivity changes with exposure to infrared light, this gives it a use in infrared detectors. Thallium was discovered by Sir William Crookes via spectroscopy. Its name Thallium comes from the Greek word thallos, which means green twig. Thallium and its compounds are toxic and can cause cancer.

Thallium compounds are used in rat and ant poisons. Also it is used for detecting infrared radiation.
