The Creator

Dmitri Mendeleev created the Periodic Table

He decided to create a table of elements while constructing a text book

The Organization of the Periodic Table

Periods

Rows

Organized by the number of Atomic Orbitals

Groups

Columns

Organized by the amount of electrons in the outer shell

The Atomic Number

Is determined by the number of electrons or protons in an atom

Families

Is a Vaguer Grouping

Organized by similar physical and chemical properties

Alkali Metals, Alkaline Earth Metals, Transition Metals, Halogen Gases, Noble Gases, Post Transition Metals, Metalloids, Nonmetals, Lanthanoids, Actinides
