Radioactive alkali metal
WebThe configurations show that the ultimate shells of alkali metals have one s electrons (s 1 electron) while the penultimate shell contains eight (s 2 p 6) electrons (Li is exception).When this valence–shell electron is lost, the alkali metals are converted into M + ions which have inert gas configuration. Since the additional electron enters ns–orbital, these are s–block … Webalkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table.
