WebOct 20, 2024 · Dobereiner discovered that the relative atomic mass of the middle element in each triad was close to the average of the relative atomic masses of the other two elements. This gave other scientists a clue that relative atomic masses were important when arranging the elements. He discovered what became known as Dobereiner’s triads. WebThe modern periodic table. an atomic number is the number of protons in the nucleus of an atom. elements are arranged in order of increasing atomic number. Periodic tables show relative atomic masses, Ar, rather than atomic masses. These are the weighted mean mass of the atoms of each element, compared to one-twelfth the mass of a carbon-12 atom.
