John Alexander Newlands, an English chemist, proposed the law of octaves in.
Newlands was one of the first to identify a pattern in the properties of the elements
Newland's Law of Octaves states that the properties of every eighth Element, starting from any Element, are a repetition of the properties of the starting Element only if they are arranged in ascending order of their atomic masses.
This law is valid only up to Calcium.
Therefore, the Law of octaves is proposed byJohn Alexander Newlands.
