Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The chart to the right gives the isotope name, element name, number of protons, and number of neutrons of three isotopes. 1. What do you notice about the isotope number and the sum of protons and neutrons? 2. The element symbol for uranium-238 is . This means U-238 has a total mass of 238 and contains 92 protons. Write the element symbols for the isotopes in the table: Hydrogen-1 Carbon-12 Uranium-235 Gizmo Warm-up The Nucle...

Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. In the image to the right, note a dozen eggs, a dozen donuts and a dozen roses. How many of each item do you have? 12 2. Would a dozen of each object have the same mass? no 3. Suppose you have a dozen carbon atoms, a dozen gold atoms, and a dozen iron atoms. Even though you have the same number of each, would you expect them all to have the same mass? Explain. No, just because they have the same quantity doesn’t mean they weig...

Part 0: Prior Knowledge Check -------------------------------- 1. On the image at right, the two magnets are the same. Which paper clip would be harder to remove? Magnet B because there is less blocking the magnetic pull As the book thickness increases the ability of the magnet to hold on to and attract paper clips decreases. Name: Student Exploration: Periodic Trends Directions: Follow the instructions to complete your group's section of the simulation. Respond to the questions and promp...
