False.
Alkaline earth metals and alkali metals are both groups of elements on the periodic table, but they have different electron configurations.
Alkali metals (Group 1, e.g., lithium, sodium) have one electron in their outermost (valence) shell.
Alkaline earth metals (Group 2, e.g., beryllium, magnesium) have two electrons in their outermost shell.
Therefore, the valence shells of alkaline earth metals generally possess fewer electrons than those of alkali metals.
