Chemistry - PERIODIC TABLE Question with Solution | TestHub

Beryllium (Be) has an exceptionally high melting point (1287°C) due to its very small atomic size and high charge density, which creates exceptionally strong metallic bonds.

All other alkali metals (Li, Na, K, Rb, Cs) and alkaline earth metals (Mg, Ca, Sr, Ba) listed have significantly weaker metallic bonding and larger sizes, resulting in lower melting points. Therefore, none of the given elements exceed the melting point of Be.
