    The mass number is the sum of the protons and neutrons

    64 = #protons + #neutrons

    Find the number of protons given the number of neutrons

    64 = #protons + 33

    #protons = 31

    In a neutral element (such as this), the number of electrons equals the number of protons

    #electrons = #protons

    #electrons = 31
