Periodic table

A little more than a century ago, the chemist Dmitri Mendeleev published an early form of the periodic table, which organizes the known elements of our world. His method of classifying the elements was so useful that we still use it even today. We will learn to apply this elegant table to an understanding of atomic structure and properties, including periodic table trends.

How are the elements organized in the periodic table? This tutorial will cover the classification of elements including groups, transition metals, and valence electrons.
