The latest release of the Periodic Table (dated 4 May 2022) includes the most recent abridged standard atomic weight values released by the IUPAC Commission on Isotopic Abundances and Atomic Weights (), compiled as part of the 2021 Table of Standard Atomic Weights 2021.For elements that lack isotopes with a characteristic isotopic abundance in natural terrestrial samples, the mass number of ...
The periodic table has undergone numerous revisions and refinements since its inception, with the modern version organized based on the number of protons in an element’s nucleus (i.e., its atomic number). It remains a fundamental tool in chemistry, helping scientists predict the properties and behavior of elements, and enabling them to design ...
The periodic table of the chemical elements is a tabular method of displaying the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869. Mendeleev intended the table to illustrate recurring ("periodic") trends in the properties of the elements.

Valence electrons: 3. A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-block, p-block, d-block, and f-block. Atomic Number.
