    Which of the following has the highest first ionization energy?

    A)  B                  

    B)       Li                   

    C)       Be                 

    D)       C

    Correct Answer: D

    Solution :

    The ionization energy of Li, Be, B and C is 520, 899. 801, 1086 kJ/mol respectively. Hence, carbon has the highest\[I{{E}_{1}}.\] Hence, the correct option is (d).
