Scientists have develop tables similar to the periodic table of elements but for molecules. Atomic number describes the number of protons in one atom of that element. Each element has a fixed position on the Periodic Table. The element symbol is always almost accompanied by other information such as atomic number and atomic weight. The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. chemical symbols. The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. In this simplistic view, the half-life of the formats is determined exclusively by their molecular size and whether they bind to FcRn. These tables will be four-dimensional, as the molecules will be arranged based on four parameters: groups, periods (like in the normal periodic table), species (according to constituting elements) and families (determined by the number of atoms). Their approach could be used for predicting novel stable substances and creating useful materials. The modern statement of this relationship, the periodic law, is as follows: the properties of the elements are periodic functions of their atomic numbers.
