Answer 1

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.
