About some regularities of chemical distribution elements in living organisms

A huge number of regularities combined by the Periodic Law allow us to predict the behavior of substances in various processes. The internal structure of the periodic system reflects the distribution of chemical elements as the charge of atomic nucleus increases. The way the fundamental characteristics of atoms change in groups from top to bottom and in periods from left to right, it reveals a deep relationship of atom properties in relation to each other, and, thus, it allows us to consider them as a whole. The fundamental characteristics are ionization potentials, electron affinity energy, electronegativity, radii of atoms and ions, and others. Integrity is the property of a system that changes when the properties of its individual components change. The periodic table fully reflects the systematic approach to study of chemical elements. Establishing patterns of changes in the fundamental characteristics of atoms in periods and groups allows us to better understand the phenomenon of periodicity, the nature of the transition of quantitative relations to qualitative ones.
