JEE Main & Advanced Chemistry Classification of Elements and Periodicity in Properties / तत्त्वों का वर्गीकरण एवं गुणों में आवर्ति Sample Paper Topic Test - Periodic Table

  • question_answer
    Sodium can't exhibit + 2 oxidation state because its second ionisation potential value is

    A) zero                 

    B) equal to first

    C) less than first                                   

    D) much higher than the first

    Correct Answer: A

    Solution :

    [a] \[I{{E}_{2}}\] of Na is extremely high because after the removal of one electron, inert gas configuration is obtained. As a result sodium cannot show an oxidation state of +2.
