Lesson: History of the Periodic Table Chemistry
In this lesson, we will learn how to describe the history of the periodic table and the organization of elements by atomic number and other parameters.
Dmitri Mendeleev developed the first periodic table to allow for elements yet to be discovered. Why did he leave gaps where others did not?
During the early 1800s, scientists attempted to understand the chemical elements by sorting them. Which property of the elements was used to order them?
Periodic tables have been around for over a hundred and fifty years and some of them look very different from the one we have today. What is it about periodic tables that makes them periodic?
