Which law was based on notes of the music?

The correct answer is the Law of octaves.

Key Points

• ​Law of octaves was based on notes of the music.
• The 56 elements that were known at the time were attempted by British scientist John Newlands in 1864.
• Based on their atomic masses, he sorted them in ascending order and saw that every eighth element shared comparable characteristics. This observation led to the formulation of Newland's law of octaves.
• According to the law of octaves, every eighth element possesses characteristics that are identical when the elements are ordered in ascending order of atomic mass.

Additional Information

• Newton law
  • ​According to Newton's first law of motion, an external force must be applied in order for an object to begin moving, stop moving, or change direction.
  • Inertia is the ability of large entities to resist changes in their state of motion. The law of inertia is another name for the first law of motion.
• Mendeleev law
  • ​Mendeleev organised the elements in horizontal rows, increasing the order of their atomic masses until he discovered an element whose characteristics matched those of the first element. 
• Modern periodic law
  • ​According to the Modern Periodic Law, an element's chemical and physical characteristics are periodic functions of its atomic number.
  • The elements with identical properties reoccur after predetermined regular intervals if elements are put in increasing atomic number sequence.
