How many d orbitals are in an ion?
5
1 of 14
All the d orbitals in an ion are...
Degenerate
2 of 14
What does degenerate mean?
Of equal energy
3 of 14
How do ligands form a coordinate bond?
Donate a non-bonding pair of electrons
4 of 14
What causes the five d orbitals to split?
A ligand approaches the metal ion by an axis and as it approaches, the non-bonding pair of electrons repels two of the d orbitals, causing them to split
5 of 14
Where do the orbitals go once they have split?
Three to low energy regions and two to high energy regions
6 of 14
What determines the wavelength of light emitted?
The difference in energy between the two energy regions where orbitals were scattered
7 of 14
If a certain colour is absorbed by an aqueous solution, what colour will be emitted?
The complimentary colour
8 of 14
What factors affect the amount of orbital splitting?
Transition metal, ligands and oxidation state
9 of 14
What sort of group is CO?
Carbonyl group
10 of 14
If the splitting increases...
The energy of light absorbed increases
11 of 14
If the energy of light absorbed increases...
The wavelength of light absorbed decreases
12 of 14
Which colour has the largest wavelength?
Red
13 of 14
Which colour has the shortest wavelength?
Purple
14 of 14
