    Question

    How many electrons are in a sodium atom?

    1. 11
    2. 22
    3. 33
    4. 12

    Hint:

    In a neutral atom number of protons and electrons are equal.

    The correct answer is: 11

      • In a neutral atom number of protons and electrons are equal.
      • Atomic number = number of protons.
      • Atomic number of sodium is 11, as number of electron is same as number of proton hence number of electron in sodium is 11.
