JEE Main & Advanced Chemistry Classification of Elements and Periodicity in Properties / तत्त्वों का वर्गीकरण एवं गुणों में आवर्ति Question Bank Electron Affinity

  • question_answer
    Nitrogen has lower electron affinity than its preceeding element carbon because

    A) Electron affinity decreases along a period

    B) Electron affinity generally increases along a period

    C) Nitrogen atom has half filled p-orbital

    D) Nitrogen is a p-block element

    Correct Answer: B

    Solution :

    Flourine although have highest electronegativity due to its very small size, effective inter electronic repulsions are observed which brings down its electron affinity.
