The concept of chemical periodicity is central to the study of inorganic chemistry there is no single best form of the periodic table because the choice depends on the purpose for which the table is used.
5 periodic properties of elements however, he pointed out the periodicity of properties, and sometimes rearranged the elements, thus reversing the order based on atomic weights furthermore, the situation was complicated because the procedure for determining the atomic the electron configuration of elements influences not only the chemical properties of elements but also their physical properties.
