atomic number 3 (pronounced /ˈlɪθiəm/) is the chemical fixings with atomic number 3, and is represented by the symbol Li. It is a soft alkali metal with a silver-white colour. Under bar conditions, it is the lightest metal and the least dense solid segment. Like in all alkali metals, atomic number 3 is higher(prenominal)ly reactive, corroding pronto in moist air to form a black tarnish. For this reason, lithium metal is typically stored under the cover of oil.[1] When cut open, lithium exhibits a metallic lustre, but contact with oxygen quickly turns it back to a dull sil rattling grey color. lithium is also highly flammable.
According to theory, lithium was one of the very few elements synthesized in the Big Bang; its abundance is this instant vastly less than that predicted by theory[2]; the processes by which new lithium is created and destroyed, and the true value of its abundance[3] continue to be active matters of examine in astronomy.[4][5][6] Though very light in atomic weight lithium is less common in the reality than any of the maiden 20 elements due to its low thermonuclear binding energy.
Due to its high reactivity it only appears course on Earth in the form of compounds.



Lithium occurs in a number of pegmatitic minerals, but is also commonly obtained from brines and clays; on a commercial scale, lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride.
Trace amounts of lithium argon present in the oceans and in some organisms, though the element serves no apparent biological function in humans. Nevertheless, the neurological effect of the lithium ion Li+ makes some lithium salts helpful as a class of mood stabilizing drugs. Lithium and its compounds have several other commercial applications, including heat-resistant glass and ceramics, high strength-to-weight alloys used in aircraft, and lithium batteries. Lithium also has classical links to nuclear physics: the splitting of lithium atoms was the first man-made form of a nuclear...If you want to get a full essay, order it on our website: Orderessay
