  1. Bell-Ringer • Please put your homework on the left corner of your desk • Get a board, marker/chalk, and a wipey thing • Take out your Reference Tables and prepare for review • Your test will be NEXT CLASS

  2. Review Game Eureeka Atomic Structure

  3. What is similar about a proton and a neutron? • They are in the nucleus • They have a similar mass

  4. History . . . . • What did the Greeks think all things were made of? • Who believed atoms looked like Plum Pudding? • What does the Gold Foil Experiment prove? • Why is the solar system model of an atom not perfect?

  5. Which of the following elements has the greatest nuclear charge? • He • N • H • C

  6. 2

  7. 2. Which sub-atomic particle in electrically neutral? Neutrons

  8. Vocabulary • Define ion- An element with a positive or negative charge • Define isotope- • An atom with the same number of protons but a different number of neutrons as another atom

  9. 5. Which species has a negative charge? • A lithium ion • An alpha particle • A beta particle • An aluminum ion

  10. 3

  11. Which of the below nuclei is an isotope of 10 p 11 n 1. 9 p 11 n 11 p 10 n 2. 10 p 9 n 3. 11 p 12 n 4.

  12. Why are atomic masses not whole numbers? • They are the average of the masses of all the isotopes

  13. What does the outermost principal energy level of Oxygen look like? • Orbital notation please

  14. 1s22s22p4 1 2 s s p

  15. Which has a completely filled 3rd Principle Energy Level? • K • Zn • Ca • Ar

  16. Zn

  17. What is the maximum number of electrons a single orbital in the 3d sublevel may contain? • 5 • 2 • 3 • 4

  18. 2

  19. As an S-2 ion loses two electrons and becomes an S0 atom, the number of protons in the nucleus • Increases • Remains the same • Decreases • I don’t know but Mole Day is wonderful

  20. If it’s Sulfur, it will have unchanging protons 2

  21. Elements over which atomic number on the periodic table are radioactive?* 83

  22. As an atom in the excited state returns to the ground state, what happens to the energy of the atom?

  23. What is the total number of electrons in a Mg atom?* 12 What is the total number of electrons in a Mg+2 ion?* 10

  24. A particle is coming out of a radioactive source. What is the radioactive particle?

  25. Draw the electron configuration for fluorine?

  26. Draw an orbital notation for Magnesium • How is the Reference Table e-1 configuration related to yours? • How many orbitals are completely filled? • How many sublevels are filled? • What is the valence shell? • Could you identify the valence shell without drawing it? • Draw the Lewis-Dot diagram

  27. If the two elements below are mixed, what will the emission spectra look like?

  28. That is the end of the game • Tally your points and wait in suspense to see who wins • If you want a copy of these questions, pick them up from the chair in front of my room during activity period
