This is a slide show about the Organization of the Periodic Table of the Elements

1. Elements and their properties

2. Review: Elements, compounds & mixtures Physical vs. chemical properties Organization of the periodic table Introduce:

3. Elements Compounds & Mixtures

4. Element: only one type of atom Elements, compounds & mixtures Carbon atom Hydrogen molecule

5. Compound: two or more elements chemically combined Elements, compounds & mixtures Sugar Molecule (C6H12O6) Jmol: an open-source Java viewer for chemical structures in 3D. http://www.jmol.org/ Water Molecule (H2O)

6. Elements, compounds & mixtures Mixture: two or more substances mixed together Bisayan lady, Jelly Beans, 3/14/08, creative commons: attribution, non-commercial, share alike Agricultural Research Service, Orange Juice, 12/11/05, Public Domain
