  1. Dot Structures

  2. Which sublevel consists of 5 orbitals • s • p • d • f

  3. Which sublevel is made of dumbbell shaped orbitals? • s • p • d • f

  4. How many electrons fill the f orbitals • 2 • 6 • 10 • 14

  5. How many electrons fill the 3rd main energy level? • 2 • 8 • 18 • 32

  6. What is the correct electron configuration for P • 1s22s22p63s23p6 • 1s22s22p63s23p4 • 1s22s22p63s2 • 1s22s22p63s23p3

  7. What is the correct end configuration for Ba • 7s2 • 6s1 • 6s2 • 5s2

  8. Excited Configurations • When electrons are in the excited state, their configuration will look different Ne ground 1s22s22p6 excited 1s22s12p63s1 or 1s22s22p43p2

  9. Valence Electrons • Electrons in the last main energy level • These are the electrons farthest out on the atom • These will interact with other atoms • These are the electrons involved in chemical reactions • There are a maximum of 8 valence electrons

  10. How to find valence e- • Write configuration and count electrons in last main energy level • Examples: Find valence electrons for C

  11. How many valence electrons does P have?

  12. How many valence electrons does K have?

  13. How many valence electrons does Fe have?

  14. How many valence electrons does Kr have?

  15. How many valence electrons does Mn have?

  16. Dot Structure • Shows valence electrons • Dots are placed around the symbol of the element • Max of two dots per side • Must have at least one dot per side before doubling up

  17. Draw Dot Structure C Fe Cl
