This English scientist noticed that the properties of elements repeat with every eighth element. He attempted to arrange the elements using the octave as a basis in 1864. Who was he?
This German chemist was a contemporary of Dmitri Mendeleev in that he also discovered the relationship between atomic mass and elemental properties. However, he did not publish his results in time. What was his name?
In spite of Mendeleev's version of the periodic table being accepted, it contained a fundamental flaw. Ordering the elements by atomic mass led to some elements being out of place. In 1913, an English chemist decided to order the elements by their atomic numbers. Who was this man?
The statement that there is a periodic repetition of physical and chemical properties of the elements when arranged by increasing atomic number is known as what?
The Mendeleevian Rule
The Lavoisier Principle
