Question 3
What were the limitations of Newlands' law of octaves?

Answer 1

Limitations of Newlands' law of octaves:

• It was applicable to lighter elements and not throughout the entire arrangement.
• Many elements discovered in future, did not follow the law of octaves.
• Cobalt and nickel were placed in the same slot and in the same column with fluorine, chlorine, and bromine even though they possess different properties.
• Iron with similar properties as cobalt and nickel was not placed with them.
