YES AND NO When using Relative Atomic Mass (Mr), a proton weighs the same as a neutron. This is rounded to the nearest whole number, however. The actual weight of â¦ a proton is 1.0073 amu. The actual weight of a neutron is 1.0087 amu. As you can see the neutron actually has slightly more mass (weight) than a proton has.
Calcium's atomic weight of 40.078 rounds to a mass number of 40. Subtracting 20 from 40 yields a result of 20. This means an atom with 20 protons and 20 neutrons must be an atom of calcium. In some cases, calcium does not have 20 neutrons.
