Since the isotopes of an element have slightly different mass numbers, it calculates the atomic mass by obtaining the mean of the mass numbers for its isotopes. From the periodic table you can see that carbon has an atomic number of 6, which is its proton number. The periodic table achieved its modern form through the work of the German chemist Julius Lothar Meyer (1830–1895) and the Russian chemist Dimitri Mendeleev (1834–1907), both of whom focused on the relationships between atomic mass and various physical and chemical properties.
