MCQ
Transition metals are not characterized by
- ✓fixed valency
- Bcoloured compound
- Chigh melting and boiling points
- Dtendency to form complexes
✓
Answer
Correct option: A.
fixed valency
a
They do not have fixed valencies since they also have vacant orbitals due to which they show exciting property and when they loose/radiate their energy they impart color in the visible region and also due to availability of vacant orbitals it show wide oxidation numbers and hence make many complex compounds.
