    Choice-B is the correct one.

    - - The atomic number is the number of protons in the nucleus.

    - - Each proton in the nucleus is usually matched by one electron in the 'cloud'.

    - - The addition of a proton OR a neutron increases the mass number by 1.

    - - Electrons have such small mass that they don't figure into the atomic mass at all.
