Answer 2

Answer:

• The ‘Law of Octaves’ was given by the ‘English chemist’, John Newlands.

• According to ‘Newland’s Law of Octaves’, every “eighth element” has similar “physical and chemical properties” when the elements are arranged in “increasing order” of their “atomic weight”.

• This periodic or repeated pattern of properties exhibited by the elements was first detected by Newland.

There were limitations to this law like;

1. It was not able to be applied to elements with higher atomic masses.
2. Two or more elements were sometimes placed in “the same slot”.
3. The grouping was done of elements with dissimilar properties.
