Document Summary

First online lecture (electron configuration)- friday (sep 22). This lecture corresponds (roughly) to section 8. 2 in your textbook. Videos and online tutorial assessments (ungraded) will be open wed, sep. 20, 2:00 pm fri sep 22, 1:00 pm. We will cover the online lecture material and spend the rest of the time solving problems. The online assessment will be open on friday sep 22, 2:00 pm to. Tuesday sep 26, 11:59 pm: 1 attempt, 40 minutes. First 3 quantum numbers (cid:159) atomic orbital n = (cid:1005), (cid:1006), (cid:1007), (cid:1008) (cid:102) (cid:34) = (cid:1004), (cid:1005), (cid:1006), (cid:894)n 1) principle quantum # Angular momentum quantum # named ____________________ determines___________________________ size, energy level named ____________________ determines ___________________________ Shape of the orbital m(cid:34) = (cid:34), ( (cid:34) + (cid:1005)(cid:895), , (cid:1004), , (cid:34) named ____________________ determines ___________________________ Fourth quantum number, ms ms- spin quantum number ms = (or spin down) , + (or spin up) gives us info speci cally about the electron.
