Periodic Table

Different Periodic Tables

• Mendeleev’s Periodic Table

• Modern Periodic Table

• What is the difference?

2 ways to organize

• Groups that run vertically

• Periods that run horizontally

Groups and Periods

• Elements in the same group have the same number of valence electrons as well as same properties.

• Elements in the same periods are in the same energy level.

3 Main Types of Elements

Metals

Nonmetals

Metalloids
