This table is a work in progress. Mendeleev's periodic table, the horizontal rows are called periods and vertical columns are called groups. The periodic table of chemical elements (abbreviated periodic table) is well known to anyone who has ever entered into the scientific laboratory or classroom. He is probably best known for his version of the periodic table of chemical elements. The noble gases (helium, neon, argon etc.) were not discovered until much later, which explains why there was a periodicity of 7 and not 8 in newlands table. Mid molar masses of elements were known. It is at once evident that such regularities very much simplify the study of chemistry. Dmitri mendeleev's periodic table, his 1869 and 1871 table, his predictions, history.
