Homework Help

Postby Celine 1F » Wed Oct 23, 2019 12:21 pm

Can someone explain number 1E.7 to me? The problem asks to determine whether each of the following electron configurations represents the ground state or an excited state of the atom
given and gives us a diagram in the book.

One way to look at it would be that the ground state of an electron would be the normal electron configuration. If the electron configuration is off in any way such as electrons being paired while the orbitals are not yet completely filled, then the electron is considered to be in an excited state.

In my opinion, the easiest way to start this question would be to write out the ground state e- configuration, then you can compare the two and see if you find any differences. Any differences would suggest the e- has been excited.

For this problem all you really have to look at is whether or not the electrons are put into orbitals properly. There should be one electron in each orbital before pairing all in the same direction and s- orbitals should fill completely before moving on to p- orbitals

You should also look at if the spins are all in the same direction for an orbital filled with just parallel electrons to make sure it is in the ground state.
