Question

A & B are two elements having similar properties which obey the law of octaves. How many elements are there in between A and B? *

Answer 1

Answer:

Six

Explanation:

There are six elements between A and B . Since A and B are the two elements having similar property and obey the Newland's Law of Octave, the number of elements between A and B, including both, must total eight.

Answer 2

Answer :

According to the law of octaves, those with similar physical and chemical properties occur after each interval of seven. Thus if A is the first element and B is the eighth element, the number of elements in between A and B is 6.
