Answer Question

1 Answer - Sort by: Date | Rating

    Sodium is a chemical element and its symbol is Na. The number of neutrons in an atom of sodium is equal to the difference of atomic mass and atomic number of the sodium atom. The atomic number of sodium is 11. The atomic mass of sodium is 23. The number of neutrons is calculated as;

    Atomic number = 11

    Atomic mass = 23

    Number of neutron = atomic mass - atomic number

    Number of neutrons = 23 - 11

    Number of neutrons = 12

    So, there are 12 neutrons present in an atom of sodium.
