MCQ
Transition metals are good electrical conductor because $.......$
- AThey are metals.
- BThey are solids.
- ✓They have free electrons in outer energy levels.
- DThey are hard.
✓

Correct option: C.
They have free electrons in outer energy levels.
Transition metals have free electrons in outer energy levels because $d-$orbitals shields poorly and due to this they acts as good conductor of electricity.
