Thallium

Description:
Thallium, with the CAS number 7440-28-0, is a soft, malleable metal that belongs to group 13 of the periodic table. It has a silvery-gray appearance and is known for its high density and low melting point. Thallium is relatively rare in the Earth's crust and is primarily obtained as a byproduct of mining and refining other metals, such as lead and zinc. It exhibits a range of oxidation states, with +1 and +3 being the most common. Thallium compounds can be toxic, particularly thallium(I) salts, which have been historically used in rodenticides and insecticides. The metal is also known for its ability to form stable complexes with various ligands. In terms of applications, thallium is utilized in the electronics industry, particularly in the production of infrared detectors and certain types of glass. Due to its toxicity, handling thallium requires strict safety precautions to prevent exposure. Overall, thallium is a fascinating element with unique properties and significant industrial relevance, albeit with associated health risks.
