Excited vs. Ground State

Postby Alyssa_Wieand_2G » Thu Oct 20, 2016 10:32 pm

Hi, I just need a little bit more clarification on the difference between the electron configurations of an excited atom and a ground state atom similar to the problem 2.39 on the homework in the textbook. How can you discern between the two?

Ground state just means that the electron is in the lowest energy form possible. That means that the electron is in the orbital we would normally expect it to be. Excited states are when electrons are not in the correct orbital.

So, in 39 for example, the carbon is excited because the second 2p electron is in the Px orbital as opposed to the Py orbital. This is an example of when the excited electron is not in the correct orbital. You can follow this same logic to solve the other ones. Hope this helps!
