Presentation Transcript

  1. Catalyst • 1. Write the order of the orbitals until you get to 5p. (Start with 1s, etc.) • 2. What orbital is phosphorus (P) in? • 3. What orbital is vanadium (V) in? • 4. How many electrons fit into each p orbital? • 5. How many electrons fit into each s orbital? • 6. How many electrons fit into each d orbital?

  2. Catalyst • 1. How many valence electrons are in silicon (Si)? • 2. Draw the Lewis Dot Structure for silicon. • 3. What is the full electron configuration for bromine? • 4. Now, what is the noble gas electron configuration for bromine?

  3. Update • Missing Week 12 Packets • 1st: Elexis, Quentavious, Khaleah, Reginald • 2nd: Chris, Devante, Johnerica, Anthony, Knicole • 3rd: None! • Missing Week 12 Quiz • 1st: Quentavious, Khaleah • 2nd: Mickey, Johnerica, Devante, Keveyon, T’erra, Anthony • 3rd: None!

  4. Today’s Agenda

  5. Oxygen • Electron configuration tells us the same thing as orbital notation • It’s just an easier, shorter way of doing it Increasing Energy 1s 2s 2p 3p 3s 4s 3d 4p

  6. Titanium Increasing Energy 1s 2s 2p 3p 3s 4s 3d 4p Electron configuration? 1s2 2s2 2p6 3s2 3p6 3d2 4s2

  7. Electron Configuration with Ions 1s22s22p63s23p5 Chlorine OR Sulfur -1 OR Phosphorus-2 These all have the same number of electrons!

  8. Today’s Agenda

  9. Noble Gas Notation! • Is used to save time when writing out electron configurations What is the electron configuration for Mn? 1s22s22p63s23p64s23d5 [Ar]4s23d5

  10. Noble Gas Notation Broken down! For Mn: Write the electron configuration for Ar. And directly under that write the electron configuration for Mn Ar: Note how these are the same!! 1s22s22p63s23p6 Mn: 1s22s22p63s23p64s23d5 So we can shorten Mn by substituting [Ar] for the part that is Ar

  11. Ar: 1s22s22p63s23p6 Mn: 1s22s22p63s23p6 4s23d5 So the orbital notation for Mn is… [Ar] 4s23d5

  12. To write the Noble Gas Notation Noble Gas Notation: *Noble Gases are the elements in the last column of the periodic table 1. Write the noble gas that comes before element in brackets [ ]. 2. Continue writing the electron configuration for element as normal

  13. What noble gas is closest (and before)…? • Se  • P  • Mg  • Al  • Be  • C  • K 

  14. So the noble gas configuration would be… • Se  • P  • Mg • Al 

  15. So the noble gas configuration would be… • Be  • C  • K 

  16. Today’s Agenda

  17. Exit Slip 1. What is the noble gas closest to and before chlorine? • Neon • Argon • Chlorine • Sulphur 2. What is the electron configuration for P? • 1s2 2s2 2p6 3s2 3p6 • 1s2 2s2 2p6 3s2 3p3 • [Ne] 3s2 3p3 • Both B and C 3. True or false: Noble gases are the elements in the first column of the periodic table 4. Name the neutral element that would have the same electron configuration as O-2 5. True or false: Argon is a noble gas

  18. Exit Slip 3 Name the neutral element that would have the same electron configuration as O-2 4. True or false: Argon is a noble gas 5. What is the electron configuration for P? • 1s2 2s2 2p6 3s23p6 • 1s2 2s2 2p6 3s2 3p3 • [Ne] 3s2 3p3 • Both B and C
