What is the formula for thallium III sulfide?
Thallium is an element on the periodic table. It's atomic number is 81.Because it is an element, I don't understand what you mean by "its formula".The symbol for Thallium is Tl, so the formula would be Tl...If you want the formula for a compound with thallium, that's a different story.It is not a diatomic element, if that's what you meant.For more information on thallium, go tohttp://en.wikipedia.org/wiki/Thallium
What is the formula for thallium carbonate?
Tl2CO3
What is thallium 201?
simple meaning. tallium are an metal or isotop that is used as a medical aid.thallium 201 a radioactive isotope of thallium having a half-life of 3.05 days and decaying by electron capture with emission of gamma rays (0.135, 0.167 MeV); it is used as a diagnostic aid in the form of thallous chloride Tl 201.or if you go wikipedia.Thallium is a chemical element with the symbol Tland atomic number 81. This soft gray poor metal resembles tin but discolors when exposed to air. The two chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861 by the newly developed method of flame spectroscopy. Both discovered the new element in residues of sulfuric acid production.Approximately 60-70% of thallium production is used in the electronics industry, and the remainder is used in the pharmaceutical industry and in glass manufacturing.[2] It is also used in infrared detectors. Thallium is highly toxic and was used in rat poisons and insecticides. Its use has been reduced or eliminated in many countries because of its nonselective toxicity. Because of its use for murder, thallium has gained the nicknames "The Poisoner's Poison" and "Inheritance Powder" (alongside arsenic).
