Have the electrons been added to this diagram from lowest to highest energy states? Yes or No? Why?

This is an orbital diagram:
I don't have arrows so,
< means up
> means down

<< <> <> <> <
4s 3d

See your later post.

You did not answer this question: yes or no. It is the same orbital diagram used from the other problem.

Sorry. I saw all of the <<, <> etc and figured it was the same question. My second response to your later question clears this up. No is the answer.

To determine if the electrons have been added to the diagram from lowest to highest energy states, we need to understand the filling order of electrons in atomic orbitals.

In general, electrons fill atomic orbitals following the Aufbau principle, which states that electrons fill the lowest energy orbitals first before moving to higher energy orbitals. Additionally, the Pauli exclusion principle states that each orbital can accommodate a maximum of two electrons with opposite spins.

Looking at the orbital diagram you provided, we can see that the 4s orbital is filled before the 3d orbitals. This is because the 4s orbital has a lower energy level than the 3d orbitals. So, the first electrons will go into the 4s orbital before moving on to the 3d orbitals.

Based on the diagram, it appears that the electrons have been added correctly from the lowest to highest energy states. The two electrons are placed in the 4s orbital, and the remaining electrons are distributed among the 3d orbitals.

Therefore, the answer to your question is "Yes, the electrons have been added to this diagram from lowest to highest energy states."
