 * 1) **History of Atom**
 * Find out the important scientists who contributed to our current knowledge of the atom.**
 * **Democritus**
 * **Lifespan: 460 BC - 370 BC (90 years-old)**
 * **Formulated an atomic theory for the cosmos.**
 * Find out the important experiments that were used to make breakthrough discoveries.**
 * **Robert Oppenheimer headed the "Manhattan Project" to create the atomic bomb.**


 * Include years of each discovery/experiment so we can get an idea of how long this process has taken.**
 * **Manhattan Project: 1942-1946.**

2. **Atomic Structure**
 * Parts of an Atom**
 * **Electrons: negatively charged**
 * **Protons: positively charged, located in nucleus**
 * **Neutrons: neutral, more like protons, also located in nucleus.**
 * **Nucleus: tiny center of an atom; includes protons and neutrons**
 * **Isotope: atoms that have the same number of protons and different numbers of neutrons**


 * Particles that make up Atoms**
 * **Electrons**
 * **Protons**
 * **Neutrons**


 * Location of Parts and Particles**
 * **Inside an atom. Subatomic level.**


 * What Makes Atoms of Different Elements Different:**
 * **There are different numbers of protons, neutrons, electrons. Atomic number is also different. Same with the properties of them.**
