Question

How beryllium differs from other elements of its group?

Answer 1

Beryllium is different from other alkaline earth metals in many characteristics. 

This is due to small size of Beryllium atom and Be+2 ion, it's high ionization enthalpy and high electronegativity and the absence of d-orbitals.

Also it has higher melting and boiling points compared to other elements in group.

The oxides of beryllium, are amphoteric whereas other oxides of alkaline earth metals are strong bases.

Answer 2

beryllium symbol is Be
