how does it occur in nature?
In nature it is mostly found with potassium-based minerals in clays, soils, and granites.
Thallium
Although thallium is a modestly abundant element in the Earth's crust, with a concentration estimated to be about 0.7 mg/kg, mostly in association with potassium-based minerals in clays, soils, and granites,
what is thallium? A chemical element. what are its characteristics? A thallium atom has 81 electrons arranged in the configuration [Xe]4f5d6s6p. It is malleable and sectile enough o be cut with a knife at room temperature. It has a metallic luster. how many isotopes does it have? 41. how is it produced? It is obtained as a by-product of smelting of copper, zinc, and lead ores. is it used in medicines? It is used for stress tests for risk stratification in patients with coronary artery disease. what are the symptoms of the disease that you just mentioned? Angina, shortness of breath, sweating , nausea or vomiting and lightheadedness. can the element you mentioned before be used in electronics? Yes, it is used in photoresistors. what are these? A passive component that decreases resistance with respect to receiving luminosity on the component's sensitive surface.. is the element you mentioned before toxic? Yes, and in cases fatal. has anybody ever died from it? Yes. can you please name some compounds that it is part of? Organothallium compounds like trimethylthallium and triethylthallium. how does it occur in nature? In nature it is mostly found with potassium-based minerals in clays, soils, and granites.

Thallium [SEP] Occurrence and production
The thallium is leached either by the use of a base or sulfuric acid from the material. The thallium is precipitated several times from the solution to remove impurities. At the end it is converted to thallium sulfate and the thallium is extracted by electrolysis on platinum or stainless steel plates. The production of thallium decreased by about 33% in the period from 1995 to 2009 – from about 15 metric tonnes to about 10 tonnes. Since there are several small deposits or ores with relatively high thallium content, it would be possible to increase the production if a new application, such as a hypothetical thallium-containing high-temperature superconductor, becomes practical for widespread use outside of the laboratory.
