1. CH 5/6 REVIEW Blue = Questions for prize points Pink = review of concepts (notes???) Can only use planner, no book or internet!

2. 1. Write the electron configuration and orbital notation for an Oxygen atom 30 seconds

3. An orbital notation is the boxes and arrows 1s2s2p An electron configuration is the superscripts: 1s 2 2s 2 2p 4

4. 2. Write the electron configuration and orbital notation for an Oxygen ion. 30 seconds

5. O -2 An orbital notation is the boxes and arrows 1s2s2p An electron configuration if the superscripts: 1s 2 2s 2 2p 6

6. Ions Atoms will gain or lose electrons to try and become like a noble gas….ie, a complete outer energy level of electrons That goal is 8 electrons in the outermost shell (+) ions have lost electrons (-) ions have gained electrons

7. Add the following ion charges to your periodic table….

8. 3. Draw a periodic table and label: group and period

9. Groups go down Periods go across

10. 4. If wavelength = 3.4 x 10 -7 m, what is the frequency?

11. Light as a wave Which wave will hit wall first? Which wave has a longer wavelength? Which wave has a higher frequency?

12. Light as a wave C= constant = speed of light = 3 x 10 8 m/sec Wavelength = meters Frequency = Hertz or 1/sec

13. 3 x 10 8 = 3.4 x 10 -7 (v) V= 8.8 x 10 14 Hz or 1/sec

14. 5. Draw which direction ionization energy increases arrows on a periodic table to show

15. + +

16. Ionization Energy Ionization energy is the amount of energy needed to take an electron from an atom. If removing an electron helps to make the atom “happy” (8 outer electrons) it is easy to do. If removing an electron makes an atom “unhappy” or “unhappier” then it is hard to do (further from 8 outer electrons) The further the electrons are from the nucleus, the easier they are to remove (less energy to do so)

17. 6. Which atom on the periodic table has the highest ionization energy of all ? (ignore the noble gases)

18. Fluorine

19. 7. Which atom on the periodic table is the easiest to remove electrons from?

20. Francium

21. 8. Draw arrows on periodic table to show how electronegativity increases.

22. + +

23. Electronegativity Amount of pull an atom has on electrons The higher the electronegativity, the more an atom can PULL the electrons towards it

24. 9. Which atom on the periodic table has the highest electronegativity?

25. Fluorine

26. 10. Which element on the periodic table has the lowest electronegativity?

27. Francium
