Answer 1

The law that English chemist John Newlands noticed, where the properties of elements repeated every eighth element when arranged by increasing atomic mass, is called the law of octaves.

Step-by-step explanation:

The law that English chemist John Newlands noticed, where the properties of elements repeated every eighth element when arranged by increasing atomic mass, is called the law of octaves. Newlands observed that similar elements appeared in the periodic table in groups of eight, much like the musical octave. This observation was one of the early attempts to classify elements and laid the foundation for the modern periodic table.
