Periodic table. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Moseley made revisions to the periodic table that resolved some of the problems with Mendeleev's version. The original periodic table of the elements published by Dimitri Mendeleev in 1869 arranged the elements that were known at the time in order of increasing atomic weight, since this was prior to the discovery of the nucleus and the interior structure of the atom. The periodic table is an arrangment of the chemical elements ordered by atomic number so that chemical periodic properties of the elements (chemical periodicity) are made clear. The Commission was established in 1899 (yes, in eighteen ninety nine) and is now operating under the Inorganic Chemistry Division of IUPAC. It organizes elements according to an idealized orbital filling (instead of valence). 74, No. Mendeleev Periodic Table.
