What is incorrect about this orbital diagram?
Both arrows in the 2p box should be pointing up
There is nothing incorrect with this diagram
In the 2p box there should only be 1 electron in the first 2p box and one in the 2nd 2p box pointing in the same direction.
All the arrows should be pointing up.
