... atoms. Let’s take Na and Cl for example. They are both on n=3. But Cl has 17 protons pulling on n=3 and Na only has 11 protons pulling on n=3. Cl is smaller because it’s nuclear charge is greater. That fact is very important for the trends. Once we can see that the nonmetals tend to be smaller with ...
