Question

drawback of newland octave rule ??​

Answer 1

hala mate,

The drawbacks of Newland's law of octaves are as follows:

• There was no proper place for hydrogen.
• Transition elements were not considered for octaves.
• The observation made by Newland does not hold well for those elements which lying beyond Ca. After Calcium,every eighth element did not possess properties similar to that of the first.
• The elements that were discovered later could not be fitted into the law of octaves.
• After the discovery of Nobel gases,it became difficult to fit them in Newland's periodic table.

Hope it helps….
