Periodic Table and Periodic Trends

Periodic Table and Periodic Trends. Periodic Table of the Elements. is an arrangement of the elements according to their properties. It enables chemists to classify the elements so that it is possible to identify patterns and trends in their properties.

Introducing the Elements

Introducing the Elements. The Element Song. 1869: Dmitri Mendeleev. Russian chemist Arranged elements in tabular form so that elements with similar properties were in the same column When listed in order by mass, elements generally repeat properties in groups of 8 (Law of Octaves).

Trends in the Periodic Table

Trends in the Periodic Table. Atomic radius. The best measure of atomic radius is the bond radius. Measure the distance between the nuclei of 2 atoms bonded together and divide by two. Going down a group, the atomic radius increases.
