MCQ
The cause of periodicity of properties is
- AIncreasing atomic radius
- BIncreasing atomic weights
- CNumber of electrons in the valency orbit
- ✓The re-occurrence of similar outer electronic configuration
✓
Answer
Correct option: D.
The re-occurrence of similar outer electronic configuration
d
Due to similar outer electronic configurations the properties of elements are also similar and hence they show periodicity.
