  1. October 1415 warm ups 1415 Keefe

  2. Warm Up 10.1 • Name the group(s) with mostly radioactive elements • Clear everything off your desk and have a calculator, pen/pencil ONLY left out: ready to quiz?!?

  3. We will burn things

  4. Warm up 10.2 • What is the charge on the following ions? • Zinc • Silver • Cadmium • Boron • Calcium

  5. Warm up 10.3 • Give the shapes of the first three orbitals.

  6. Warm up 10.6 • Turn in the 2 thangeties we worked on Friday and GET OUT YER NOTES • Which rule, if any, is violated by this orbital diagram: • Which rule, if any, is violated by the following orbital diagram:

  7. Warm up 10.7 • GET READY TO DO YO LAB! Get out the HW • Which element is represented by the following orbital diagram? • Which element is represented by the following orbital diagram?

  8. Warm up 10.8 • Light with a frequency of 7.26 x 1014 Hz lies in the violet region of the visible spectrum. What is the wavelength of this frequency of light? • When an electron beam strikes a block of copper, x-rays of frequency 1.07 x 1019 Hz are emitted. What is the wavelength of these x-rays? • Formula:  λν = c

  9. Warm up 10.8 Solution: • λν = c ∴ λ= c/ν λ= _3.00 x 108 m/s 7.26 x 1014 Hz λ= 4.13 x 10-7 m

  10. Warm up 10.9 • The radio station KUSC (in Southern California) broadcasts at a frequency of 91.5 MHz. Calculate its wavelength in meters. • Convert MHz to s¯1 •  Use λν = c

  11. Warm up 10.9 Solution • Convert 91.5 MHz to Hz: 91.5 MHz x 1000000 Hz 1 MHz = 9.15 x 107Hz

  12. Warm up 10.9 Solution • λν = c ∴ λ= c/ν • λ = 3.00 x 108 m/s 9.15 x 107Hz λ= 3.28 m

  13. Warm up 10.10 • Turn in your warm ups and spectra labs and get ready to do the lab! • GAME FACES- WE HAVE 45 MINUTES TO FINISH!!

  14. Warm up 10.13 • Arrange the following elements from longest to shortest wavelength based on the flame test images below:

  15. October 14 • TEST DAY! • Everything except a calculator, something to drink, and pen/pencil goes on the floorat the back of the room.

  16. October 15 • Name the seven diatomic elements (HINT: BrINClHOF) • SHOWING YOUR WORK, convert 4.31 cm to inches where 1 cm=0.394 inches

  17. Warm up 10.16 • Which is more electronegative in each pair? • Ca or Ga • Mg or Ra • F or I • B or Tl • At or Br

  18. Warm up 10.17 • Tell whether the following will increase in size or decrease in size as ions: • Yttrium • Magnesium • Copper • Sulfur • Bromine • Neon

  19. Warm up 10.20 What are the names for the phase changes represented by the numbers 1, 2 , 3 and 4 in the diagram above?
