Answer 1

The law of octaves states that every 8th element, when arranged by atomic mass, has similar properties.

Step-by-step explanation:

The law/rule that states that when arranged by atomic mass, every 8th element has similar properties is called the law of octaves.

This law was proposed by the Russian chemist Dmitri Mendeleev when he developed the periodic table in the 19th century.
