A lithium atom is an atom of the chemical element lithium. Stable lithium is composed of three electrons bound by the electromagnetic force to a nucleus containing three protons along with either three or four neutrons , depending on the isotope , held together by the strong force .
Lithium forms salt-like derivatives with all halides and pseudohalides. Some examples include the halides LiF, LiCl, LiBr, LiI, as well as the pseudohalides and related anions. Lithium carbonate has been described as the most important compound of lithium. [101] This white solid is the principal product of beneficiation of lithium ores.
Lepidolite is associated with other lithium-bearing minerals like spodumene in pegmatite bodies. It is the major source of the alkali metal rubidium . [ 13 ] In 1861, Robert Bunsen and Gustav Kirchhoff extracted 150 kg (330 lb) of lepidolite to yield a few grams of rubidium salts for analysis, and therefore discovered the new element rubidium.
Lithium is a highly reactive alkali metal that is widely used in various industrial applications due to its unique properties. Lithium compounds are formed by combining lithium with other elements, such as oxygen, sulfur, and chlorine, to form different chemical compounds.

The difference is whether the lithium-7 produced is in the ground state or an excited state, respectively. The total energy released going from 7 Be to stable 7 Li is about 0.862 MeV, almost all of which is lost to the neutrino if the decay goes directly to the stable lithium.
Every 1% by mass of lithium added to aluminium reduces the density of the resulting alloy by 3% and increases the stiffness by 5%. [1] This effect works up to the solubility limit of lithium in aluminium, which is 4.2%. Strain hardening Introducing another type of atom into the crystal strains the lattice, which helps block dislocations. The ...
