What is deltaE=hv (transition metals)

Hey!

I was just wondering if anyone could give me the lowdown on deltaE = hv
(h=plancks constant and v=frequency of absorbed radiation)

It is to do with the colours of transition metals and I have just read about it in my specification. I am not exactly sure what I need to know about it but if anyone could help me at all id be grateful thanx :smile:

E is the energy of the photon emitted when an electron moves from a higher orbital in the transition metal to a lover 1...the photon emitted is y they have colours....but u dnt need to knw any of that unless ure doing A2 fysix :smile:

Ok... in the d-sub shell in transition metals there are two slightly differing energies.

Electrons in the 'ground state' that is the lower energy level can absorb energy in the visible (or UV) part of the spectrum so that it can be 'excited' and go into the higher energy state.

The energy change is proportion to the frequency of the light absorbed, which is where the delta E = hv equation comes from.

Also, it is the colour that is NOT absorbed that is the colour of a solution. So, take hexaquacobalt (II) which is pink in solution, the solution doesn't absorb the pink light cuz you wouldnt see it as pink then. It absorbs the complimentary colour, which is the opposite colour that is seen. It's very confusing, i know!
