1. The problem statement, all variables and given/known data What are the two possible electron orbital configurations of W+6, Au+, and Au+3. 2. Relevant equations 3. The attempt at a solution I know Tungsten should initially be [Xe]6s2 4f14 5d4 and Gold should initially be [Xe]6s1 4f14 5d10. From what I remember of intro chem one configuration for W+6 was [Xe]6s1 4f12 and for the other I said [Xe]6s2 4f7 5d5 but does that make any sense? I have doubts. For Au I said Au+ was [Xe]6s1 4f14 5d9 and Au+3 was [Xe]6s1 4f14 5d7. Am I on the right track? I used to know this but it was years ago and I've forgotten much of it.
