4E: 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 by ionization energy and electron affinity. 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 atoms and molecules in this tutorial. Hydrogen, helium, lithium, beryllium, boron, carbon…
