Newland's law of octave: According to Newland's law of octave when elements are arranged in ascending order on the bases of their atomic masses and he observed that every eighth element had property similar to that of the first element.
Newlands compared the similarity between the elements to the octaves of music, where every eighth note is similar to the first.
Based on this observation, Newland’s law of octaves was made.
Newland divided the elements into horizontal rows and each horizontal row had 7 elements in it.
Example:The eighth element of lithium is sodium and the eighth element of sodium is potassium, and all three have similar chemical properties.
