WebThe real development in the periodic table took place after the development of Mendeleev periodic table. He gave a law which states that “The properties of an element are the periodic function of their atomic masses”. He arranged elements in periods (horizontal rows) and groups (vertical columns) in the increasing order of atomic weights. WebThe periodic table below shows the metallic elements and the general at-a-glance trend. In general, as we move down and to the left, elements become more metallic. Importance of Periodic Trends Periodic trends are observable patterns in the properties of an element that are dependent on its position in the Periodic Table.
