Chapter 5: The Periodic Law

History of the Periodic Table

A Brief History of the Development of the Periodic Table – from Mendeleev to Rutherford and Moseley, have a look at the history of the periodic table we know today.

(Main Idea: Mendeleev’s periodic table grouped elements by their properties; Modern periodic tables arrange the elements by both atomic number and properties.)

A discussion of the building blocks and precursors to the periodic  table, as well as the ‘fathers’ of the modern periodic table.
