Alkalimentals : Silver-gray solids that are soft enough to cut with a knife
Sodium : Only alkali metal manufactured on a large scale
Lithium : Potassium is produced by a similar process
Sylvite : This is a source of potassium like KCI
Purealkalimetals : Stored under oil because they will tarnish to exposure to oxygen
ns1 : Alkali metals have and electron configuration that ends in this
Francium : Alkali metal discovered in 1939 by Marguerite Perey
Rubidium : Alkali metal discovered in 1861 by Robert Bunsen & Gustav Kirchhoff
Valence electron : The presence of a single one of these explains the low melting points and boiling points in alkali metals
Ionic halide : All alkali metals react with halogens to form this
Alkalisolution : All alkali metals react with water to form this.
Cesium : Metal used in photocells
Potassium : Produces a light blue flame
NaC1O : used as a bleach and to disinfect swimming pools
Salt : Coins were made of this in China at one point
Plus1 : Alkali metals for ions with this charge
NaOH : This is used as a drain cleaner
hydride : Lithium this is a convenient source for hydrogen
Electrolytes : Sodium in energy drinks help maintain this
Meltingpoint : Cesium has a low of this at only 28 degrees Celsius
