Lithium notes

Lithium is a chemical element with atomic number 3 and the symbol Li

Lithium is made up of three electrons bound by the electromagnetic
force to a nucleus containing three protons along with either
three or four neutrons which depends on the isotope.

It is a soft, silver-white alkali metal.

Under standard conditions, it is the lightest metal
and the lightest solid element.

And like all alkali metals, lithium is highly reactive and flammable.
 lithium is therefore usually stored in a hydrocarbon sealant,
 often being petroleum jelly.

Lithium will ignite and burn in oxygen when exposed to water or water vapors.
 As with all alkali metals, lithium fires are difficult to put out,
 requiring dry powder fire extinguishers.

Lithiums melting point is 180.50 degrees celcius.
And it's boiling point is 1330 degrees celcius.

The metal is produced through electrolysis from a mixture of fused
55% lithium chloride and 45% potassium chloride at about 450 degrees celcius.

Naturally occurring lithium is composed of two stable isotopes, 6Li and 7Li,

Lithium is a good conductor of heat and electricity.

Lithium's coefficient of thermal expansion is twice that of aluminium and almost four times that of iron.

Lithium is the only low numbered element that can produce net energy through nuclear fission.

Uses:
 Lithium has important uses in nuclear physics.
 Lithium metal is often used in coolants for heat transfer applications.
 In heat-resistant glass and ceramics.
 lithium grease lubricants.
 Flux additives for iron.
 steel and aluminium production.
 Silicon nano-welding.
 lithium batteries.
 And lithium-ion batteries.
  Because of its low atomic mass, it has a high charge- and power-to-weight ratio.
