The periodic table of chemical elements (abbreviated periodic table) is well known to anyone who has ever entered into the scientific laboratory or classroom. Petersburg, russia because he published the first version of the table in 1869. Dmitri mendeleev has invented the periodic table which arranges all the chemical elements in a proper way that is in the order of increasing atomic predictions and gaps in this way of arranging elements mean there are gaps in his horizontal rows that are called 'periods'.
