    Elements Se, Cl and S have been arranged in the order of increasing ionisation energies. Identify the correct order.

    A)  \[S<Se<Cl\]

    B)  \[Se<S<Cl\]

    C)  \[Cl<S<Se\]

    D)  \[Se=S<Cl\]

    Correct Answer: B

    Solution :

     lonisation energy generally increase from left to right across a row of the Periodic Table and decreases from top to bottom down a group. Hence, IE of CI > S and IE of Se < S. Thus, the order is Se < S < Cl.
