THALLIUM My element was atomic number 81. It is atomic morsel 81. It has 81 protons and electrons and 123 neutrons. atomic number 81 has a messiness of 204.3833 atomic mass units. Its symbol is Tl. It resides in group IIIA of the periodic table. That is the aluminum family. thallium has a bluish touch after exposure to the air. It is a very soft and malleable metal. It has an electron configuration of 1s22s23s23p64s23d104p65s24d105p64f145d106s26p1. It has 6 electron shells. It melts at 576.7 K and boils at 1730 K. It is a consentaneous when at room temperature. Â Â Â Â Â Â Â Â thallium was discovered in 1861 by a British pill roller and physicist. His name was Sir William Crookes. He discovered it spectroscopically in England. He scattered it.

Â Â Â Â Â Â Â Â thallium does not have umteen uses. It is utilize in photocells because of the galvanising conductivity of thallium sulphide. atomic number 81 was originally used to plugger treat ringworm and umpteen other skin infections. It was consequently limited because of the narrow valuation reserve between the benefits and its health risks. thallium bromide-iodide crystals be still used as infrared detectors. thallium sulphate used to be widely used as a pesticide and an ant killer.
It was scentless and tasteless and worked well, but it was nitty-gritty to be too toxic. atomic number 81 slats which burn with a glazed green flame are used in flares and rockets. thallium is the 60th most torrential element in the Earths crust. in that respect are 3.6 separate of atomic number 81 in every one thousand million parts of the Earths crust. Thallium compounds are super toxic. The negative cause are cumulative and can be taken in by means of the skin. Poisoning from Thallium takes several(prenominal) days to effect you and when...
