I was wondering how you determine which orbital is less energy when drawing a molecular orbital energy diagram (i.e. N 2s vs. O 2s)? Thank you in advance.

I believe that the more electronegative atom has a lower energy level.
So in that case, oxygen would have a lower energy level than nitrogen because oxygen is more electronegative.

One of my TA's also told me that another way of determining which orbital is less energy, is by asking yourself which element has a higher Z value. The higher the Z value, the lower in energy it'll be.
