Question

The placement of elements in the Newland’s table was compared to:
A. weeks of a month
B. notes of music
C. months of a year
D. days of a month

Answer 1

Hint: Newland found out that every eighth element in the grouping resembles each other and put forward the law of octaves, in which we can see that he arranged all the elements known at that time in order of relative atomic mass into periodic table.

Complete Solution :
  - As we know that ‘octo’ means eight. Andin music we can see that every eighth note is similar to that of the first note.
- It is found that in musical notes there is a repetition of the same note after a gap of seven. Alexander
 - Newland observed that when he arranged lighter elements in order of their increasing atomic masses, then every eighth element was the same as that of the first one just like the eighth note of a musical scale.
- And it is found that this relation is called Newland's law of octaves.
- Hence, we can conclude that the correct option is (b), that is the placement of elements in the Newland’s table was compared to notes of music.
So, the correct answer is “Option B”.

Note: - This law was found to be applicable only till calcium, after that every eighth element doesn’t match to the first element.
- As the noble gases were discovered, the properties of the 8th element were no longer found to be the same as those of the first one.
