Q. The main reason for showing anomalous properties of the first member of a group in s or p-block is
Classification of Elements and Periodicity in Properties
A
maximum chemical reactivity
14%
B
maximum electronegativity and different configurations
18%
C
small size, large charge/radius ratio
54%
D
tendency to form multiple bonds.
14%
Solution:
Due to small size, large charge/radius ratio and high electronegativity, the first element shows anomalous behaviour.
