Exempel på alkali metal

• These sources work by applying a layer of alkali metal atoms on a low work function substrate, usually tungsten.

• The technique coats a tungsten plug with aluminosilicate doped with an alkali metal, which is then sintered onto the tungsten.

• These alkali metal heat pipes transferred heat from the heat source to a thermionic or thermoelectric converter to generate electricity.

• From this acid other alkali metal salts can be prepared.

• Saltiness and sourness are perceived when alkali metal or hydrogen ions enter taste buds, respectively.

• As a hydride of an alkali metal, it is reactive towards even weak oxidizing agents.

• The alkali metal peroxides and superoxides are powerful oxidizing agents.

• This natural radioactivity became a basis for a mistaken claim of the discovery for element 87 (the next alkali metal after caesium) in 1925.

• Hence, the larger alkali metal atoms (further down the group) will be less electronegative as the bonding pair is less strongly attracted towards them.

• All of the alkali metal fluorides, and most of the alkali earth metal fluorides are true salts.

• When alkali metal cyanides are used, at least partial neutralization of the reaction medium is usually necessary to provide desired products.

• The number of states of rare gas halides is greater than that of alkali metal salts.

• The radius increases sharply between the noble gas at the end of each period and the alkali metal at the beginning of the next period.

• The alkali metal magnetometer is very expensive to use but it is very sensitive and has fast cycles when it is used.

• Inducing n-type doping within the silicene structure requires an alkali metal dopant.
