Thallium nuclear reactor
Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air. Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, … See more A thallium atom has 81 electrons, arranged in the electron configuration [Xe]4f 5d 6s 6p ; of these, the three outermost electrons in the sixth shell are valence electrons. Due to the inert pair effect, … See more Although thallium is a modestly abundant element in the Earth's crust, with a concentration estimated to be 0.7 mg/kg, mostly in association with potassium-based See more Thallium and its compounds are extremely toxic, with numerous recorded cases of fatal thallium poisoning.
