2. In electron configurations for multielectron atoms, the orbitals are listed from lowest to highest energy. That being said, the order shows that the 5s orbital is listed before the 4d orbitals in a "proper" electron configuration. Please explain why this orbital ordering is unexpected and why it is believed to occur.

One bit of evidence that the quantum mechanical model is correct lies in the magnetic properties of matter. Atoms with unpaired electrons are attracted by magnetic fields and thus are said to exhibit pararamagnetism. The degree to which this effect is observed is directly related to the number of unpaired electrons present in the atom. Consider the ground-state electron configurations for Li, N, Ni, Te, Ba, and Hg. Which of these atoms would be expected to be paramagnetic, and how many unpaired electrons are present in each paramagnetic atom?

The outermost electron in an alkali-metal atom is sometimes described as resembling an electron in the corresponding state of a one-electron atom.
