4. Student Learning Objectives EQ: Do I recognize that all matter consists of atoms? (SPI0807.9.1) TOC: 49. Electron Shells Foldable 50. Drawing an Atom

5. Atom’s Family

6. Student Demo Helium Lithium Hydrogen

7. Brain Pop!!!

8. 49. Electron Shells Foldable 1 st level holds only 2 electrons

9. Electron Shells 2 nd level can hold only 8 electrons 1 st level must be full to move on to level 2

10. Electron Shells 3rd level hold up to 18 electrons 2 nd level must be full to move to level 3

11. 50. Drawing an Atom Your team will use the periodic table to find the following information to move the electrons where they go on the shells for each element. You are to write the information in your SNB and draw the placement of the electrons. Materials: Shell diagrams Felt balls (electrons) SNB Periodic Table Atomic Number Atomic Mass Number of Protons Number of Neutrons Number of Electrons

12. 1. Oxygen Atomic Number – 8 Atomic Mass – 16 # of protons – 8 # of neutrons– 8 # of electrons – 8 2. Lithium Atomic Number – 3 Atomic Mass – 7 # of protons – 3 #of neutrons– 4 # of electrons – 3 Practice these with your group on the paper with the dots

13. 3. Fluorine Atomic Number – ___ Atomic Mass – ___ # of protons – ___ # of neutrons – ___ # of electrons – ___ 4. Silicon Atomic Number – ___ Atomic Mass – ___ # of protons – ___ # of neutrons – ___ # of electrons – ___ Practice these with your group on the paper with the dots

14. 5. Boron Atomic Number – ___ Atomic Mass – ___ # of protons – ___ # of neutrons – ___ # of electrons – ___ 6. Chlorine Atomic Number – ___ Atomic Mass – ___ # of protons – ___ # of neutrons – ___ # of electrons – ___ Practice these with your group on the paper with the dots

15. Complete the worksheet for Drawing an Atom on your own. Turn it in to your class tray when finished.

16. Exit Ticket The number of protons is the same as the number of electrons. True or False? Explain your answer. The number of protons is always the same as the number of neutrons. True or False? Explain your answer.
