Question

why alkali and alkaline earth metals are most reactive elements of the periodic table??​

Answer 1

Answer:

All alkaline Earth metals have similar properties because they all have two valence electrons. ... When valence electrons are farther from the nucleus, they are attracted less strongly by the nucleus and more easily removed from the atom. This makes the atom more reactive. Q: Alkali metals have just one valence electron.

Answer 2

Answer:

because they have low ionization energies

EXPLANATION:

Group IA and IIA elements are called alkali and alkaline earth metals.they are very reactive because they have loq ionization energies and therefore have a greater tendency to lose electrons

they have general electronic configuration of ns1 and ns2 in their valence shell.Due to their reactive nature they are never found in the free state.and they are kept under a liquid such as kerosine oil.
