You are about to begin a journey to find thesecrets of the Periodic Table
The Periodic Table is a majestic tool used by
scientists all over the world
Are you ready?

The Periodic Table
Key Point #1: The periodic table organizes the elements into many different groups based on physical and chemical properties.
We will learn about the major ways to group the elements – by… Family Metals/metalloids/nonmetals Valence Electrons Atomic size Electronegativity

What does PERIODIC mean?
Key Point #2: Periodic means that there is some kind of pattern.
In the Periodic Table, there are numerous patterns What about in regular life? How could you group
the following items in different ways?

The Evolution of the Periodic Table
Just like atomic theory, the Periodic Table also has a long history
In the late 1790s, French scientist Antoine Lavoisier compiled a list of elements known at that time - only 23!
In the 1800s, scientists began discovering a ton of elements - up to 70!

Evolution Continued
New elements meant new data!
Scientists needed a way to organize everything!

John Newlands (1860s)
Arranged the Periodic Table by increasing ATOMIC MASS
Noticed patterns based on physical and chemical properties - repeated every 8th element

Periodic Law
Periodic Law is the statement that there is a periodic (patterned) repetition of chemical and physical properties of the elements when they are arranged in increasing atomic number
