This is a site that is supposed to help people learn about the structure of the atom. It is also supposed to clear up any misconceptions about how the atom is organized and what it is made up of. This article talks about the particles that make up the protons and neutrons in the nucleus, and how electrons really orbit the an atom. This site is all about atoms and how the forces within them work, allowing them to bond together. I would recommend this site to anyone who wants to learn more about atoms, it has more information than we go into in class, so it would be helpful to anyone who wants to do extra work.

Lecture 2's emphasis is on the hydrogen atom. The lecture specifically addressed the binding energies of the electron and nucleus, verification of hydrogen-atom energy levels and wavefunctions or orbitals (for the hydrogen atom), explained using the Schrödinger equation and diagrams.

This is an extremely helpful site! It gives you the information that you need for the periodic table, such as the atomic numbers and groupings, but it also is an interactive table! If you click on the element you will be given an in depth description about the element and it will even tell you all of the groups it is in as well as different classifications. I would definitely recommend this to someone who is interested in chemistry and wants to learn about the different elements.
