Parts of the Periodic Table Part 2

​John Newland

​Newland noticed that when looking at elements, every 8th element has similar properties. Because it was every 8th element that repeated their properties, he called this the Law of Octaves.

​Meyer and Mendeleev

​They organized the periodic table by atomic mass and their properties. This made it possible for Mendeleev to be able to predict what future elements to be discovered, such as Gallium.

​Mosely

​After many more elements were discovered and the atomic number was discovered, the periodic table was reorganized by Henry Mosely. The periodic repetition of chemical and physical properties of the elements when they are arranged by increasing atomic number is called the periodic law.
