  1. Warm-UpFebruary 20, 2013 • Write down the date and objective. • Objective: SWBAT write electron configurations notation and identify an element based on its electron configuration by competing in Battleship. • Complete the following warm-up: • Is Lithium (Li) more similar to Sodium (Na) or Beryllium (Be)? Explain your reasoning. • What group are the noble gases?

  2. Objective & Agenda • Objective: SWBAT write electron configurations notation and identify an element based on its electron configuration by competing in Battleship. Agenda • Tattoo/Body Art • Review Homework • No Excuses Wednesday • Quantom Mechanical Model & Electron Configuration • Practice • Electron Configuration Battleship • Exit Slip

  3. Pick an element from the periodic table and it will become the centerpiece of your tattoo. Surround the element with artwork that demonstrates how these elements are used in real life. You can include the symbol, atomic number, group/family, classifications, etc. Write two paragraphs explaining how your artwork represents the element. The best location of the tattoo on your body must be written underneath the tattoo. Use at least 3 colors on your tattoo. Tattoo/Body Art

  4. Homework 12 Review

  5. What If? • You were one of 12 brother and sisters. • You had little discipline growing up and had to repeat both the 1st and 2nd grade. • Your mother was a crack addict and your father was killed in jail. • Spent time in and out of foster homes and endured times of homelessness. • Wanted to play football, but had to pull up your 0.76 GPA first. • Is it worth putting in all that work?

  6. Michael Oher • Was taken in by a local family that helped him get back on track and playing football. • Increased his GPA to 2.72 by completing 10-hour college courses from BYU. • Was a star at Ole Miss, and was drafted by the Baltimore Ravens with the 23rd pick in the 2009 draft. • The movie “The Blind Side” was based off of him.

  7. Quotes • “People like to talk about "Cinderella stories," but Cinderella didn't get her happy ending without lifting a finger. She had to show up at the ball, be charming and smooth, and win over the prince. Of course she had help along the way, but ultimately it was up to her to make the fairy-tale ending happen.” • (In reference to watching The Blind Side) "People ask me if it was hard looking back, remembering the hard times. It taught me a lot and I learned so much from it that it made me a better person."

  8. Quantum Mechanical Model • AKA Electron-Cloud Model • Orbital-region of space in which there is a high probability of finding an electron. • Each energy level (denoted by n = 1,2,3,or 4) contains sublevels. • The energy level represents how many sublevels there are in each energy level. • EX: n=1 has 1 sublevel (s) n=2 has 2 sublevels (s & p) n=3 has 3 sublevels (s, p & d) n=4 has 4 sublevels (s, p, d & f)

  9. QUANTUM NUMBERS: • n = energy level • l = orbital shape • S=0 • P=1 • D=2 • F=3

  10. Examples Where are the following electrons located? n=1, l=0 n=3, l=2 n=2, l=1 n=4, l=3 n=2, l=0 Write out a possible set of quantum numbers for the following electrons Located in the 2 energy level in a p orbital. Located in the 4 energy level in a d orbital.

  11. Electron Configuration Electron configurations: explain the ways in which electrons are arranged in various orbitals around the nuclei of atoms.

  13. Example • Sulfur (S)

  14. Practice • Write the electron configuration for the following elements: • Chlorine (Cl) • Potassium (K) • Carbon (C) • Gallium (Ga) • Iodine (I)

  15. Practice (Honors) • Write the electron configuration for the following elements: • Chlorine (Cl) • Potassium (K) • Carbon (C) • Gallium (Ga) • Iodine (I) • Nobelium (No)

  16. Shortcuts! Short-Hand/Noble Gas Configuration: put noble gas directly before the atomic # of element in [ ] and then start from the beginning of the next period. EX:

  17. PRACTICAR! • Write the noble-gas electron configuration for the following elements: • Chlorine (Cl) • Potassium (K) • Carbon (C) • Gallium (Ga) • Iodine (I)

  18. PRACTICAR! (Honors) • Write the noble-gas configuration for the following elements: • Chlorine (Cl) • Potassium (K) • Carbon (C) • Gallium (Ga) • Iodine (I) • Nobelium (No)

  19. Electron Configuration Battleship (30 min.) Directions: Each person needs two periodic tables, a marker, and a manila folder. Tape the periodic table to the inside of the manila folder. Block off your “battleships” on the bottom periodic table and record your “hits” and “misses” on the top battleship. After your partner calls the electron configuration, you must call out the element to confirm it is correct and then “hit” or “miss”
