danielsw98667 2019-10-24 04:21:47 | Confused with the value of J. affordableseoservice.org | | andyferd 2010-11-12 17:35:33 | When is it correct to assume ETS is asking for the spectroscopic notation of the electron rather than the atom? In a problem on a different test they give the spectroscopic notation of an atom and ask for the state of the electron after a transition (I can't remember which other practice test it is) | | faith 2010-10-23 23:51:18 | there's ambiguity in yosun's solution although it too arrives at the correct answer.
for J
>half filled shell, J=|L+S|
< half filled shell, J=|L-S|
=half filled shell, J=S (since no net orbital momentum)
hence knowing just the value spin which is 1/2, will immediately gives the answer, B. ( and the valence electron is in sub shell s will give notation S)
to clarify S notation can be a lil confusing. S represent spins while S also is use to represent the sub shell s.
| | wikiwert 2010-09-15 21:55:13 | This excercise is solved using Hund´s Rule; this should be mentioned in the solution (for other atoms, other problems arise, as the one mentioned by student2008). | | student2008 2008-10-14 03:02:16 | Yosun, you're not quite right writing , since may take any of the values in the range , separated by 1.
Otherwise, the information about J would be redundant. | |
