Periodic Properties


The elements display a wide variety of trends.  Some are obvious, such as the general increase in atomic weight with atomic number.  Others are less obvious, such as the relationship between electron affinity and atomic number.  Some can be explained by shielding of the nucleus; just take a look at the inverse relationship between ionization energies and atomic radii for the noble gasses.  Still others are downright weird, such as the maximum observed in density while moving across a period in the periodic table.

This activity is designed to help you explore these and other elemental trends.  One of the tabs on the activity gives you an example of how to use it, but I'm sure you'll get the hang of it pretty quickly.
