उत्तर
Newlands’ Law of Octaves is applicable up to calcium.
Explanation:
John Newlands' Law of Octaves states that when elements are arranged in order of increasing atomic masses, the properties of every eighth element are similar to the first. However, this law was found to be applicable only up to calcium (the 20th element), after which the properties of the eighth element did not repeat the properties of the first.
