Structure of the Atom

From an online curriculum guide produced by New York University, this web page provides a good, introductory outline to the structure and makeup of an atom, even going into some detail about electron orbitals. Also included is a link to an interactive Periodic Table of Elements provided by WebElements. It may not be strictly related to subatomic particles, but atoms are very tiny things and the chart is pretty cool!

Build Atoms Yourself

This activity is meant to be a supplement to the "Earth Science" textbook published by McDougal Littell (now Holt McDougal), but no textbook is required to use it!

Using this simulator, you can drag'n'drop protons, neutrons, and electrons to create the first 10 elements in the periodic table, as well as most of their isotopes! (Macromedia Shockwave Player required for this website).
