A) Li
B) Be
C) B
D) C
Correct Answer: D
Solution :
The given choices belong to second period. lonisation energy increases when we move from left to right in period. Therefore, C has highest first ionization energy (lonisation energy of Li, Be, B and C are 520, 899, 801, 1086 kJ/mol respectively.)You need to login to perform this action.
