The mass number is equal to the sum of the number of protons, neutrons, and electrons. The sum of the number of the electrons and protons. ... mass number. The number of protons and neutrons is often—but not always—equal. Two atoms having the same atomic number (i.e., belonging to the same element) ... May 26, 2021 ... Step 1: Identify the element. Step 2: Find the number of protons of the element from the periodic table. The number of protons is equal to the atomic number of ... By the way, the mass of an element is not equal to the sum of the masses of ... As long as the number of atoms remains the same the relative mass does not change. respect to the mass number at 10 sccm H2 flow rate are shown in Fig. 4. In the case of the Ar/CF4 plasma, C6F9. + was maximal in intensity in the CnF2n-3. + ... As the weight of a proton and a neutron is almost equal to 1 amu in every atom, the atomic mass and mass number of an atom are almost the same.
