- 10. Two types of Ozone • Stratosphere • Troposphere
- 11. Two types of Ozone Stratosphere (good) Troposphere (bad)
- 12. What is Ozone • Oxygen • Each Oxygen atom: – 8 protons – 8 neutrons – 8 electrons
- 13. What is Ozone • Ozone is an Oxygen molecule
- 14. Atom Structure • Protons and Neutrons in Nucleus • Electrons in the cloud
- 15. Electron Numbers • A neutral atom has # Protons = # Electrons • The inner shell has no more than 2 electrons • The outer shell has no more than 8 electrons • All atoms WANT 8 electrons in the outer shell. • It makes them complete.
- 16. This atom WANTS 3 more electrons. Why? Nitrogen
- 17. This atom WANTS 5 more electrons. Why? What is an atom that it WANTS to bond with?
- 18. Al + N ALN
- 20. Two types of Ozone Troposphere (bad) This is how bad ozone is created.
- 21. Two types of Ozone Stratosphere (good) This is how good ozone is destroyed.
- 22. • Ozone Layer: A form of oxygen gas that makes up a layer of the stratosphere, where it filters out UV radiation from the sun. • The production and emission of Chlorofluorocarbons (CFC’s) is the leading cause of depletion. • A Chlorine atom is removed from the CFC and attracts 1 of the 3 oxygen atoms in the ozone molecules. • CFC’s can come from cooling systems, fire extinguishers, Styrofoam containers, home insulation, plastic foam, and throwaway food containers.
- 23. Hole in Ozone Layer The South Pole has a hole in the Ozone layer
- 24. • Stratospheric ozone hole discovered in 1975 by Sherwood Roland and Mario Molina. • Reappeared every year since then during the Antarctic winter.
