  • question_answer Which of the following property displays progressive increase with the rise in atomic number across a period in the periodic table

    A) Electronegativity

    B) Electron affinity

    C) Ionization potential

    D) Size of the atom

    Correct Answer: A

    Solution :

    Both electronegativity and electron affinity increases. This is because decrease in the size and increase in the nuclear charge. But electronegativity increases continuously.
