Options
6 and 8
7 and 15
8 and 14
6 and 13
Solution
X and Y are two elements having similar properties which obey Newlands’s Law of Octaves. The minimum and maximum number of elements in between X and Y respectively are 6 and 13.
Explanation:
- It is assumed that X and Y are two elements with comparable characteristics that adhere to Newland's Law of Octaves.
- Thus, according to Newland's rule of Octaves, those with comparable physical and chemical qualities come after each interval of seven elements, hence there are at least six elements between X and Y.
- This suggests that there are eight groupings of elements, with the ninth member having attributes identical to the first.
- As a consequence, the lowest and maximum number of elements between X and Y are 6 and 13 respectively.
