The Periodic Table and Periodic Law 6.1 Development of the Modern Periodic Table Objectives Trace the development and identify key features of the periodic table. History of the Periodic Table’s Development In the 1790’s Antoine Lavoisier compiled a list of 33 known elements. The 1800s brought...

Periods are the rows of the periodic table, groups are the columns. Every element has a unique combination of period and group, and a unique atomic number.
The periodic table of the elements is a representation of all known elements in an orderly array. The periodic law presented by Dmitri Mendeleev in 1869 stated that if the (known) elements are arranged by atomic weight, then certain trends in chemical properties can be observed. That is to ...
The Periodic Table Learning Objectives By the end of this section, you will be able to: State the periodic law and explain the organization of elements in the periodic table Predict the general properties of elements based on their location within the periodic table...
and predicted its properties. Just five years later an element with the proper atomic mass was isolated and named gallium by its discoverer. The close correspondence between the observed properties of gallium and Mendeleyev’s predictions for eka-aluminum lent strong support to the periodic law. Add...
