Writing an Electron Configuration Format

Postby DanielleNario1A » Tue Oct 23, 2018 10:54 pm

Just to clarify, when writing an electron configuration of an atom, you can write it in either way:
1s^2 2s^2 2px^1 2py^1 and/or 1s^2 2s^2 2p^2
but one is just more specific in which are parallel?

they are essentially the same thing just when if a question asked how many electrons are paired in the first way you wrote it you know the last two electrons aren't paired and are parallel

It depends on what you're being asked for. In general, the 1s^2 2s^2 2p^2 should be fine. 1s^2 2s^2 2px^1 2py^1 is more specific than you usually need because it gives you information about the spin of the electrons in the last p orbital relative to one another (electrons being in pairs or not).

Although both are correct, I believe that Dr. Lavelle prefers 1s^2 2s^2 2px^1 2py^1 over the 1s^2 2s^2 2p^2 because it gives better insight on whether or not the electrons are paired.
