October 1415 warm ups. 1415 Keefe. 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?!?. We will burn things. Warm up 10.2. What is the charge on the following ions? Zinc Silver - PowerPoint PPT PresentationTRANSCRIPT
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?!?
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:
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?
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
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
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!!
Warm up 10.13• Arrange the following elements from longest
to shortest wavelength based on the flame test images below:

• TEST DAY! • Everything except a calculator, something to
drink, and pen/pencil goes on the floor at the back of the room.
October 15
• Name the seven diatomic elements (HINT: BrINClHOF)
• SHOWING YOUR WORK, convert 4.31 cm to inches where 1 cm=0.394 inches
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
Warm up 10.17
• Tell whether the following will increase in size or decrease in size as ions:– Yttrium– Magnesium– Copper– Sulfur– Bromine– Neon
