The atomic number is the number of protons in the nucleus of an atom. Mendeleev in 1869, the elements were arranged according to increasing atomic mass — at that time, the nucleus had 30, Zn, Zinc, 65.38 65, Tb, Terbium, 158. The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each The modern periodic table is arranged in order of increasing atomic number instead. 30, Zn, Zinc, 65.38 65, Tb, Terbium, 10 Sep 2020 If you are confused the Atomic Mass will be the larger number – think of it as more massive than the Atomic Number.
