WebAtomic mass in an atom or group of an atom is the sum of the masses of protons, neutrons and electrons. The electrons have very less mass in comparison to protons or neutrons so the mass of electrons is not influenced in the calculation. For an element, relative atomic mass is the average mass of the naturally occurring isotopes of that element ... WebThe periodic table was arranged by atomic mass, and this nearly always gives the same order as the atomic number. However, there were some exceptions (like iodine and tellurium, see above), which didn’t work. Mendeleev had seen that they needed to be swapped around, but it was Moseley that finally determined why.
