  1. Question 1

    Q1. What distinguishes the first ionization energy of alkali metals from noble gases?

    • A) Alkali metals have higher ionization energy
    • B) Noble gases have stable electron configurations
    • C) Alkali metals require more energy for ionization
    • D) Noble gases have lower effective nuclear charge

    Answer: Noble gases have stable electron configurations

    Explanation: Noble gases have filled shells, making ionization less likely. Alkali metals have low ionization energy due to single valence electrons.
