Give the notation for the valence-shell configuration (including the outermost d-electrons) of ...

Do we need to know these for the all the exceptions in the periodic table?
(d) "coinage" metals (Cu,Ag,Au) is an example they use to explain this.
But what about Tungsten, Niobium, Ruthenium, Rhodium Palladium, etc.
If we were asked to give general notation for that group, how do we consider these?

In lecture, Lavelle covered only the Copper (Cu) and Chromium (Cr) exceptions to the standard electron configuration rules. I don't think you'd need to know any of the other exceptions.

I agree with Kaushal. Also, on his powerpoint, Lavelle wrote that we only need to know the s-block, the p-block, and just the first d-block row, so I don't think we will have to worry much about the other elements!
