Answer 1

Answer:

B. 56

• According to Newlands' Law of Octaves, 56 elements were assumed to exist in nature.

• He started with the element with the lowest atomic mass (hydrogen) and ended with Thorium which was the 56th element.

• He found that every eighth element has the same properties as the first. He compared it to the octave found in music.

• That's why he called it the 'law of octaves'.

• This is known as 'Newlands' Law of Octaves'.

• The properties of lithium and sodium were found to be similar in Newlands' octave.
