Question

Alkaline earth metals have higher melting points than alkali metals.
If this is true enter 1, if false enter 0.

Answer 1

Alkaline earth metals have higher melting points than alkali metals. They have two electrons in their valence shell resulting in the formation of strong metallic bonds for atom binding in the metal crystal lattice. On the other hand, alkali metals have only one electron in their outermost shell.
