State Newland's law of the octave. Support your answer with an example.

Answer 1

Newland's law of octave: According to Newland, If the chemical elements are arranged according to the increasing order of their weight, those with similar chemical and physical properties occur after each interval of seven elements.

For example:

The 8th element of lithium(Li) is Sodium(Na) and both show similar properties,

The 8th element of beryllium(Be) is Calcium(Ca), and both show the same properties.
