know morePeriodic table was first invented by Dimitri Mendeleev from Russia He had arranged the elements by increasing atomic masses His periodic table design had blanks in it because there were unknown atomic elements with the appropriate properties discovered By early 1900 s 1914 Prof Henry Moseley a British Physicist was able to determine the atomic numbers of all the known elements using an
know moreThe periodic table we use today is based on the one devised and published by Dmitri Mendeleev in 1869 Mendeleev found he could arrange the 65 elements then known in a grid or table so that each element had 1 A higher atomic weight than the one on its left For example magnesium atomic weight is placed to the right of sodium atomic weight The True Basis of the Periodic Table
