explain anamolous behaviour of beryllium ?​

Answer 1

$\huge \bigstar \mathfrak \pink {Answer :} \over$

Anomalous behaviour of beryllium :

☆ Anomalous behaviour of an element refers to the deviation of the properties and behaviour of an element from its usual or normal behaviour.

❀ Beryllium has small atomic and ionic size.

❀ The high ionisation enthalpy and small size of alkaline earth metals results in the formation of covalent compounds that are easy to hydrolyze.

❀ The coordination number of beryllium is not greater than 4 due to the presence of four electrons in the valence shell.

❀ The oxide and hydroxide of beryllium are amphoteric in nature.

Answer 2

answer:

Anomalous Behaviour Of Beryllium

Beryllium is harder than other members of its group.

Beryllium has higher melting and boiling point than other members of its group.

Beryllium does not react with water even at high temperature while other metals do. ...

Beryllium forms covalent compounds whereas other members form ionic compounds.

hope it helps u.
