Interpreting the Periodic Table Lab Report Name: Kelsey Cordero and Bruno Canteros Lab Partners: Ashley Fernandez, Lab Experiment: Interpreting the Periodic Table Date: January 15, 2015 Introduction: The periodic table is the most important chemistry reference there is. It arranges all the known elements in an informative array. Just like when entering a grocery store similar items are grouped together which makes an item easier to find. Elements are arranged left to right and top to bottom in order of increasing atomic number. The different rows of elements are called periods. The period number of an element signifies the highest energy level an electron in that element occupies. An element is a substance that is made…show more content…
Materials: (Activity 1) 1. Calcium 2. Sulfur 3. Aluminum 4. Silicon 5. Carbon 6. Paper 7. Copper 8. Pencil 9. Iron 10. Magnesium (Activity 2) 1. Periodic Table Element Cards Procedure: The whole procedure for Activity 1: 1. Provide yourself with a pencil and paper. 2. As the teacher assigns you to a station, in that station are two elements where you must describe the physical features of the element. 3. As you rotate from station to station make sure to observe each and every element clearly until you have completed all 8 elements. 4. Once you are done use your notes to help you organize the elements into groups. The Procedure Activity 2: 1. Designate a group member to retrieve the periodic table cards. 2. Look for an open space to work with your group. 3. Use the periodic table to arrange the elements in order. 4. Once ordered observe the properties in the cards and try to find any and all patterns.
