Thallium was discovered by Sir William Crookes, an English chemist, in 1861.
The formula for thallium carbonate is Tl2CO3, which consists of two thallium (Tl) atoms and one carbonate (CO3) ion.
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
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).
usually done after an exercise stress test or after injection of a vasodilator, a drug to enlarge the blood vessels, like dipyridamole (Persantine). Thallium is injected, and the scan is done then and again four hours (and possibly 24 hours) later
Nitrogen was discovered in 1772 by Daniel Rutherford
he discovered the cathode ray and also discovered the element thallium
Yes, thallium occurs naturally in the Earth's crust, typically in association with sulfide ores of heavy metals. It is a relatively rare element and is often found in small amounts as a trace element.
The most stable isotope of thallium is thallium-205, which has 81 protons and 124 neutrons. Thallium in its elemental form is a soft, malleable, heavy metal that is typically found in nature combined with other elements.
Thallium is a heavy metal that is known to be odorless. There is no distinct smell associated with thallium.
Thallium has an oxidation number of +1. Therefore, the formula for thallium carbonate would be Tl2CO3.
the overall atomic mass is 204.37, but for thallium 203 it is 203, and for thallium 205, it is 205.
No, thallium isotopes do not contain iodine. Thallium isotopes are variants of the element thallium, while iodine is a separate element with its own isotopes.
I think thallium weight about 189
Thallium has 6 electron shells.
Thallium(III) Selenide
Thallium-201 has 81 protons. This is because the number of protons in an atom is equal to its atomic number, and thallium has an atomic number of 81.
Thallium is a chemical element with symbol Tl and atomic number 81
