AI Thread Summary
The discussion centers on the placement of arrows in Hund's Rule diagrams, specifically the difference between +1 and -1 spin representations. It highlights that the order of filling orbitals does not affect the overall outcome when there is no external magnetic field, as the orbitals are degenerate. The confusion arises from differing representations in textbooks and diagrams. Ultimately, the sequence of filling is not critical as long as the principles of Hund's Rule are followed. Understanding this flexibility is key to grasping the concept of electron configuration in degenerate orbitals.

can someone help clarify something for me
in this diagram why is it that the arrow is placed in +1 first and in my textbook it is placed in -1 first?

Does it really matter? As long as there is no external magnetic field these orbitals are degenerated, so they can be occupied in any order.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
