Hey dear,
Be is a member of group 2 i.e. alkaline earth metals.
● How does beryllium differs from other elements of same group -
- Be don't have vacant d-orbitals like other elements.
- Melting & boiling point of Be is unreasonably higher than other gr.2 elements.
- Be forms covalent compounds while other elements form ionic compounds.
- Be shown CN upto 4 only while other elements of gr.2 show CN of 6.
- Be has very high polarizing power as compared to other members.
Hope this helps you...

Answer:
beryllium is the member of group 2
Beryllium differs from other members of group 2 as follows:
(1) Beryllium chloride is covalent and soluble in organic solvents. Other alkaline earth metal chlorides are ionic and insoluble in organic solvents.
(2) Beryllium chloride is strong Lewis acid other chlorides of group 2 elements are not Lewis acids.
(3) Beryllium Oxide is amphoteric, reacts with both acid and base (aqueous HCl and aqueous NaOH.) Oxides of other alkaline earth metals are basic, react with only acid (aqueous HCI).
