  1. Question 1

    Q1. Which statement about noble gases matches typical introductory exam facts about their chemistry under ordinary lab conditions?

    • A) They are generally unreactive because their valence shell is a stable closed shell in simple terms
    • B) They react like halogens because they need one electron
    • C) They are the most metallic elements on the far left
    • D) They always form +2 ions like Group 2 metals

    Answer: They are generally unreactive because their valence shell is a stable closed shell in simple terms

    Explanation: Noble gases (Group 18) have completely filled valence shells, giving them very high ionisation energies and virtually no tendency to gain, lose, or share electrons under ordinary conditions.
