Question

Metallic bonding is much stronger in alkali metals compared to alkaline earth metals.
If this is true enter 1, if false enter 0.

Answer 1

All of the elements of group two i.e. alkaline earth metals have two electrons in their outer shell. Metallic bonds in the alkaline earth metals are thus, stronger than for the alkali metals, resulting in higher melting points, but they are still quite reactive because the two outer electrons are easily lost.
