ReactivityApplicationsSources and Extraction

Lithium is a rare facet found generally in molten rock and saltwater in very small amounts. It is understood to it is in non-vital in human biological processes, although that is supplied in many drug treatments due to its positive effects on the human brain. Due to the fact that of that is reactive properties, humans have utilized lithium in batteries, nuclear combination reactions, and thermonuclear weapons.


Lithium was very first identified as a component of of the mineral petalite and also was found in 1817 through Johan respectable Arfwedson, but not isolated till some time later on by W.T. Brande and Sir Humphry Davy. In its mineral forms it accounts for just 0.0007% of the earth"s crust. That compounds are used in particular kinds that glass and also porcelain products. An ext recently lithium has come to be important in dry-cell batteries and nuclear reactors. Some compounds that lithium have been used to act manic depressives.

You are watching: How many protons neutrons and electrons does lithium have

Lithium is an alkali metal with the atom number = 3 and also an atom mass that 6.941 g/mol. This method that lithium has actually 3 protons, 3 electrons and 4 neutron (6.941 - 3 = ~4). Gift an alkali metal, lithium is a soft, flammable, and highly reactive metal that often tends to form hydroxides. It additionally has a pretty short density and also under traditional conditions, that is the least thick solid element.


Sources and also Extraction

Lithium is most generally found linked with aluminum, silicon, and also oxygen to type the minerals known as spodumene (LiAl(SiO3)2) or petalite/castorite (LiAlSi4O10). These have been uncovered on each of the 6 occupied continents, but they room mined primarily in west Australia, China, and also Chile. Mineral resources of lithium are ending up being less essential, together methods have actually now been arisen to manipulate the lithium salts found in saltwater.

Extraction native minerals

The mineral develops of lithium are heated come a high enough temperature (1200 K - 1300 K) in order come crumble them and thus allow for subsequent reactions to much more easily take it place. After ~ this process, among three methods have the right to be applied.

The usage of sulfuric acid and also sodium lead carbonate to allow the iron and aluminum come precipitate native the ore - from there, an ext sodium lead carbonate is applied to the continuing to be material allow the lithium to precipitate out, creating lithium carbonate. This is treated v hydrochloric acid to kind lithium chloride.The usage of limestone to calcinate the ore, and then leaching through water, forming lithium hydroxide. Again, this is treated with hydrochloric acid to form lithium chloride.The use of sulfuric acid, and also then leaching through water, developing lithium sulfate monohydrate. This is treated with sodium lead carbonate to kind lithium carbonate, and also then hydrochloric mountain to type lithium chloride.

The lithium chloride acquired from any kind of of the three techniques undergoes an oxidation-reduction reaction in one electrolytic cell, to different the chloride ion from the lithium ions. The chloride ions space oxidized, and the lithium ions space reduced.
