NettetThe original periodic table developed by Mendeleev in 1869 consisted of elements arranged in order of increasing atomic mass. However, it was soon discovered that arranging elements in this manner did not correlate with the position predicted by their chemical properties. In 1913, Moseley found that there was a more fundamental … NettetIn this form of a periodic table, the horizontal rows are called periods and the vertical columns are known as the groups. Groups consist of elements that have similar outer shell electronic configuration in their atoms. …
