If anyone would like a specific chemical addressed, let us know. Lithium Lithium is the lightest of the alkali metals and the lightest solid element. It is a very soft silvery metal.
Liquid lithium is less viscous than water.
It reacts exothermally with nitrogen in moist air at high temperature, has a high electrical conductivity, and is soluble in ammoma. The associated hazards are that it ignites in air near its melting point and is a dangerous fire and explosion risk when exposed to water, acids, or oxidizing agents. Lithium fires should only be extinguished with chemicals designated for this purpose. Lithium in solution is toxic to the central nervous system. Most of the common lithium based compounds such as lithium carbide, lithium fluoride, lithium nitrate and lithium hydride also demonstrate similar hazardous properties and toxicity.
