The reactivity of an alkali metal depends on the metal's ability to __________ electrons. In the alkali metals the outermost electron only feels a net charge of +1 as some of the nuclear charge (which is equal to the atomic number) is cancelled by the inner electrons; the number of inner electrons of an alkali metal is always one less than the nuclear charge. Therefore the only factor which affects the atomic radius of the alkali metals … Alkaline earth metal - Wikipedia Sat Dec 22 2001 · The alkaline earth metals are six chemical elements in group 2 of the periodic table.They are beryllium (Be) magnesium (Mg) calcium (Ca) strontium (Sr) barium (Ba) and radium (Ra). The elements have very similar properties: they are all shiny silvery-white somewhat reactive metals at standard temperature and pressure.. Structurally they (together with helium) have in common an … They should behave like normal alkali and alkaline earth metals (albeit less reactive t...
