Thallium

Thallium (Tl), a heavy, soft, gray metal belonging to the boron group, is a rare and toxic element. It exhibits properties intermediate between those of lead and mercury, but is considerably more reactive than either. thallium is primarily obtained as a byproduct of the extraction of other metals, such as zinc and lead. Its compounds are colorless and odorless, often used in specialized electronic applications, but are exceptionally poisonous, causing severe neurological damage and potentially death. Due to its high toxicity, the use of thallium is tightly regulated.
