The Periodic Table: Atomic Radius, Ionization Energy, and Electronegativity
Why is the periodic table arranged the way it is? There are specific reasons, you know. Because of the way we organize the elements, there are special patterns that emerge. And you know how Professor Dave feels about patterns. He likes...
