Lab 1: Build an Atom This lab requires the use of the Phet simulation: Build an Atom. The simulation can be accessed at: https://phet.colorado.edu/sims/html/build-an-atom/latest/build-an-atom_en.html Part 1: Click on the simulation labeled "Atom" 1. What does the yellow "X" represent? 2. What do the blue dotted line circles represent? 3. Add a proton to the atom. What element is this? 4. What is the net charge and mass number? 5. Now add a neutron to the atom. What element is this? 6. What is the net charge and mass number? 7. Explain any changes in your answers that were caused by adding the neutron. 8. Now add an electron to the atom. What element is this? 9. What is the net charge and mass number? 10. Explain any changes in your answers that were caused by adding the electron. 11. Now add a second proton to the atom. What element is this? 12. What is the net charge and mass number? 13. Explain any changes in your answers that were caused by adding the additional proton. 14. Create an Oxygen (O) atom with a mass number of 15 and a net charge of -2. How many protons, neutrons, and electrons does it have? 15. Now click on the "Symbol" simulation (at the bottom of the screen). Create the same Oxygen atom as in Q14. What does its Symbol look like? (take a screenshot and upload it with your lab document). 16. What numbers are recorded in each corner of the atomic symbol? 17. Write a 200 word summary of what you have learned about atoms from this lab and Chapter 11 in your text.
