And illuminate a world that’ll try to bring you down
But not this time
Today’s graphic looks at the colours of transition metal ions in solution, and explains why transition metals have coloured complexes/compounds.
Fun fact of the day: Mn2+ salts tend to be even fainter pink than what the figure actually shows, to the point where it looks white. This is because a lot of Mn(II) complexes are high spin, which results in one electron residing in each of Mn’s d orbitals with all having the same spin. Electron excitations in this case aren’t allowed, as a promotion would lead to two electrons with the same spin in the same orbital (which is forbidden by the Pauli exclusion principle). This results in a nearly colorless complex. :D
