Cr(4s1 3d5) Cu(4s1 3d10)
What is roughly Zeff
Z-S(Atomic number-core electrons)
What is Fajans rule?
The radii cations contract compared to neutral element, and anions expand.
IP is proportional to what?
Zeff ^2/n^2
What happens to IP when going from 3d6-3d5 and visa versa?
Lower,Higher
What is the relationship between Eaffinity and Zeff?
Zeff is high

Coordination isomerism
For a 4 coordinated metal complex, give the general formula(s) of complexes that are optical isomers
M(ABCD)
M(AB)2 (bidentate)
For octahedral, general formula for isomers?
M(A2B2C2)
M(A^A)3
MA2(B^B)2
Give the A equation, what value for a certain parameter can define if it is Laporte-forbidden?
A=ecl
e<100
What is the Aufbau principle and the Hund rule?
Which one is applied for HS?
Aufbau-Electrons poulate lowest orbital first
Hund- Electrons occupy degenerate orbitals to maximise parallel spins.
Hunds rule.
CN-,F-,H2O, what assumptions can be made for CFT?
CN- always LS, F- for 1st row all HS, H2O usually high spin.
2nd 3rd row always LS
Give 2 reasons why deltaT is less than deltaO
- No orbitals point directly at ligands
- 4 ligands rather than 6
