The main reason for showing anomalous properties of the first member of a group in s or p – block is.
A
Maximum chemical reactivity
B
Maximum electronegativity and different configurations
C
Small size, large charge/ radius ratio
D
Tendency to form multiple bonds.
Answer
Small size, large charge/ radius ratio
Explanation
Solution
: Due to small size, large charge / radius ratio and high electronegativity, the first element shows anomalous begaviour.
