The chemical elements are arranged in increasing order according to their atomic number and depending on their chemical properties in periods and groups.This poster shows the most important data of each element: the relative atomic mass, melting point, covalency radius, ionization energy, electronegativity according to Pauling, important oxidation numbers or the electron configuration. As such, it is an important tool for school and university.
