Properties that change periodically depending on the charge of the atomic nucleus.

Depending on the nuclear charge of the atom, this will change the radius of the atom, their metallic and non-metallic properties, ionization energy, valence in typical compounds, the very structure of the outer electronic layers. Each element in the periodic table is located exactly according to the increasing charge of the atom.
