|Problem Set 6|
|Fall Term 2003|
The way Logan phrased this first question in this sixth Problem Set of ours, I believe he used the old way of naming subshells, as opposed to the new way of naming subshells. If I were to name the subshells using the new system expediently presented in the website http://www26.brinkster.com/uptable/ups2.htm, I'd say that Logan's 5f subshell would be best called an 8f subshell under the new system, and that the 3d subshell, be called a 5d subshell. What is the old system's 5d subshell is nowadays a 7d subshell, and the new subshell naming system does not have anything by the name of 3d.
Such kinetic energy value I considered to be the difference between hv and the photoelectric work function adjusted to give per photon Joules values rather than per mole.We must not mistake the Greek n for the Roman v. Although both quantities are taken over time, frequency has no consideration for the dimension L for length. In calculating for nde Broglie, however, we do quite need a length value, so as to complete our determination of quantitas motus

Iodine has one unpaired electron in one of its three 5p orbitals (whether be it 5px, 5py or 5pz does not matter), and a configuration of [Kr]5s24d105p5
For Iridium we have [Xe]6s24f145d106p3 as the configuration, with all three unpaired electrons being in 6p
For Bismuth we have [Xe]6s24f145d106p3 as the configuration, with all three unpaired electrons being in 6p. Such configuration we get from Brown et al.'s Figure 6.28. The page before, we also have for Bismuth the long-hand confguration 1s22s22p63s23p63d104s24p64d104f145s25d105p66s26p3(Brown, et al., Sampble Exercise 6.9, pages 226-227).
For Gadolinium [Xe]6s25p14f7
There are how many unpaired electrons in Gadolinium? I'd say there would be eight. Most of these, seven to number, lay abouts in the 4f orbital. Gadolinium is paramagnetic. In fact, it and Iron are the only ferromagnetic elements in the entire universe.
