    A electrons Correct Answer Incorrect Answer
    B charges Correct Answer Incorrect Answer
    C nucleus Correct Answer Incorrect Answer
    D electron cloud Correct Answer Incorrect Answer

    Solution

    The nucleus contains protons and neutrons, which have much greater mass than electrons. Since protons and neutrons reside in the nucleus, it accounts for nearly all the mass of the atom. The electrons, despite their importance in chemical interactions, contribute negligibly to the atomic mass.
