CH08 – Orbitals

Dates:

• P1 – Tuesday, September 13th
• P3 – Wednesday, September 14th
• P5 – Wednesday, September 14th

Recap Homework

• full spectrum
• visible spectrum
• key equations – meaning
• focus – this is just the evidence of quantization

Practice

• E levels = 1, 20, 28, 30 (joules)
• How many lines?
• Draw quick spectrum
• (note – don’t convert to m or nm)

New Material – Orbitals

• so what do these levels look like?
• probability! of finding electron in a given location!
• activity: campus map (handout)
• indicate where you are every 10 minutes
• draw line around where you are probably
• what do the larkings mean?

But what does it LOOK like?

• described by combinations of four numbers
• n = principal QN
• l = angular momentum QN
• ml = magnetic QN
• ms = spin QN
• rules for each number
• generate a table – start with n=1

Homework

• finish the table through n = 4
