For example, how would you find the charge of Au, and why/how? Thanks!

Transitional metals have multiple possibility of charges because they have d orbitals which allows for them to go through expansion of the shell and usually, either half-filled orbitals or completely filled orbitals are the most stable conformations. For most part, in order to determine the charge of a transitional metal, you'd have to look at the anions that are bonding to the said metal. For example,
Fe(NO3)2 is iron (II) nitrate, since NO3 is a nitrate ion that has a -1 charge and there are 2 nitrates to balance the iron, therefore implying that the iron in this compound has a +2 charge. On the other hand, if the formula had be Fe(NO3)3, then the iron would have +3 charge. However, there are three transitional metals that dont have different charge possibilities, and those are, Ag (silver), Zn (zinc), and Cd (cadium). Silver always has a +1 charge and the other two always have +2 charge. So for your example, you would have to look at the compounds that it forms. Hope this helps you.

Au normally has either a +1 or a +3 charge. Check most on-line periodic tables for details
