What is the difference between a Bohr models, Lewis Dot Diagram, and the Nuclear Symbol? . 1. Periodicity . Periodic Trends . 2. Periodic Law . The chemical and physical properties of the elements are periodic functions of their atomic numbers; properties of the elements occurred at repeated intervals called periods.. The lab technician shown here is using a magnifying lens to examine a bacterial culture in a petri dish. When scientists cannot see the details of what they study, they try to obtain experimental data that help fill in the picture.. Elemental Properties and Patterns. The Periodic Law. Dimitri. Mendeleev (1869/1871) was the first scientist to publish an organized periodic table of the known elements.. He was taking a chemistry course in Russia and tried to find a way to organize the periodic table. . 4. Interpreting the Periodic Table. Typically . they have a shiny . luster..
