Why Do Uranium Electron Configurations Differ?

AI Thread Summary
Uranium's electron configuration can be represented as [Rn]7s^2 5f^4 or [Rn] 5f^3 6d^1 7s^2, leading to confusion. The difference arises from the energy levels of the 5f and 6d orbitals, which can vary based on the specific conditions and interactions within the atom. The more stable configuration typically emphasizes the lower energy state, which is why some sources list 5f^3 6d^1. Understanding these configurations is essential for grasping the behavior of uranium in various chemical contexts. Further details can be found in resources like Wikipedia.

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...
