Answer:
- This system fails because it does not hold good for all the elements discovered till date time. It is limited to only few elements.
- It does not completely explain the complete properties of elements like valency, oxidation state of elements which have variable oxidation state like phosphorus showing trivalent and pentavalent nature.
- It does not fit to transition elements.
