Activity 2 - Why Do the D-orbitals Give us Colour
... So now we know how we fill the electrons into the different orbitals we have to think about the actual electronic configuration of some transition metal complexes. Let’s go back to copper, and we’re going to think about the nice simple form, hexaqua copper, [Cu(H2O)6]2+ (here we have a Cu2+ ion and ...
