Describe oxidation state and coulor of lanthanides |
|
Answer» The colour of lanthanide ions is due to the presence of partly FILLED f ORBITALS. As a result it is possible to absorb certain wavelength from the visible region of the spectrum. This results in TRANSITIONS from one 4f ORBITAL to another 4f orbital known as f-f transition. |
