Periodic table (alternate)
Meyer ended the periods on an element of the group of alkaline earth metals. And Mendeleev ended the periods on the element of the halogen group. Therefore, in Meyer's Periodic Table of Elements there are no gaps between the first 1, 2 or 3 elements and subsequent elements in the second and subsequent periods. In the Periodic Table of Elements according to Mendeleev, the first two (after the discovery of noble gases in 1902 - three) elements hang unnaturally above the subsequent elements of the periods, there is no such incident in the Periodic Table of Elements according to Meyer.
