Name ________________________ Atomic Structure WebQuest Introduction Atoms are the basis of chemistry. They are the basis for everything in the Universe. You should start by remembering that matter is composed of atoms. If you want to do a little more thinking, start with particles of matter. Matter, the stuff around us, is used to create atoms. Atoms are used to create the elements. Elements are used to create molecules. It just goes on. Everything you see is built by using something else. The Task You are to use the suggested websites to gather information and answer the questions or statements on the sheet. Basic Atomic Structure: go to http://www.chem4kids.com/files/atom_structure.html 1. Describe how atoms are like building blocks 2. What are some of the smaller particles that make up atoms? 3. What are the three basic parts of an atom? Draw a basic picture of an atom. 4. What particles are located in the nucleus? What is the charge for each particle? 5. Where are electrons located? What is the charge for this particle? 6. If the charge on the atom is 0, what does this mean? Subatomic Particles: go to for the following http://www.qacps.k12.md.us/qhs/teachers/weedonD/atoms%20page%205.htm Nucleus: Facts: Protons: 1. Charge: 2. Facts: Neutron: 1. Charge 2. Facts: Electrons: 1. Charge: 2. Facts: Define Isotope: Give example (not from site!): Define Atomic Number: Give example (not from site!): Define Atomic Mass: Give example: (not from site!)
