Limitations of Newlands law of octaves :
1. Law of octaves only applied till Calcium.
2. He said after 56 elements no more elements will be discovered but they were discovered and didn't fit into his table.
3. He put elements with similar properties in different slots and elements with different chemical properties in same slot. For ex. Iron, fe was placed far away from Cobalt, Co which resembled its properties.
4. No slot for inert gases was left in his table.
