    B Nitrogen Correct Answer Incorrect Answer
    C Sulphur Correct Answer Incorrect Answer

    Solution

    The elements which exist as single atom are called monoatomic elements. The elements which exist in atomic pairs bonded to each other are called diatomic elements. The elements which exist as groups of more than two atoms are called polyatomic elements. Chlorine (Cl2), Nitrogen (N2) and Hydrogen (H2) are diatomic gases.
