There are a number of elements that do not follow the simple order of orbital filling. Some examples are Cr([Ar]4s^1 3d^5), Cu([Ar]4s^1 3d^10), and Gd ([Xe]6 s^2 4 f^7 5d^1). (a) Identify what is unusual about the electronic configurations of these elements. (b) Explain why these elements may have these configurations rather than the expected ones.
