Why Boron Shows Anomalous Behaviour?

Boron ,the first member of group 13 elements, shows anomalous behaviour and differ from rest of the members of its family. The main reason for this difference are : 1) exceptionally small atomic and ionic size. 2) high ionization enthalpy.

What is anomalous Behaviour of boron?

Anomalous behaviour of boron - definition

Boron is a nonmetal while other member are metals. ... Boron shows allotropy while other member do not. 3. Amongest the elements of group 13, boron has highest melting and boiling point.

Why does be show anomalous behavior Write 4 points?

Beryllium: The anomalous properties of beryllium is mainly due to its small size, high electronegativity, high ionization energy and high polarizing power compared to the other elements in the block. ... The coordinate number of beryllium is not more than 4 whereas other alkali metals have coordinate number of 6.
