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.. Fall, 2017. 2. X-ray Diffraction Image. Images like these can be used to determine crystal structures. 3. Comparison of Radii. 4. Squashed versus Unsquashed. Left, metallic or covalent radius. Right, Van der Waals radius. 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. . and . GRBs structure. Alessandro Drago. University. of Ferrara. Outline.

A Scientific Law is a summary of what is seen in observations. . A Scientific Theory is an explanation of why these observations are occurring.. Both laws and theories are tested by using them to predict what would happen in certain situations.. Pre-AP Chemistry. Charles Page High School. Stephen L. Cotton . Section 4.1 Defining the Atom.
