Directions: We will be primarily using the website http://www.chemicalelements.com to assist us with this laboratory activity. In addition, you are welcome to use other websites for further assistance. If you choose to use other sites, please include them at the end of your report! Step 1: Select 15 elements from the Periodic Table. You may choose any 15 elements, as long as they are "spread out" across the Periodic Table (do not choose 15 elements that are all right next to each other). Step 2: Create either a data table or a series of bulleted statements (not long paragraphs, please) to describe your 15 elements. All responses should be in your own words. Include the following information: 1. The name and chemical symbol of the element; 2. The atomic number and mass number of the element; 3. The Group number and Period number of the element; 4. The number of protons, neutrons, and electrons within the most common isotope of an atom of the element; 5. The electron configuration and number of valence electrons within an atom of the element; 6. The classification of the element (metal, nonmetal, or metalloid, as well as any other "special" names such as halogens, transition metals, etc. that may apply); 7. The discoverer and year of discovery of the element; 8. State in which the element is typically found (i.e., phase at room temperature and whether the element is typically found in pure elemental form or as part of a compound); 9. Uses for or applications of the element. *** Did you use any references other than chemicalelements.com to assist you? If so, please include them here:
