1. Introduction to Metals, Nonmetals and metalloids

2. Groups of elements Metals Non-metals Metalloids
Elements on the Periodic Table are categorized in 3 main groups. Each group shares similar properties and characteristics. The groups are:
Metals
Non-metals
Metalloids

3. Metals Metals make up almost 75% of the Periodic Table
Found on left side and middle of the Periodic Table (excluding hydrogen).
Characteristics:
Have luster (Shiny)
Good conductor of heat and electricity: Silver (Ag) and copper (Cu) are some of the most efficient metals and are often used in electronics.
Solids (except Mercury)
Malleable – able to pound into a shape (flexible)
Ductile – able to draw into wires.

4. Non-metals Found on right side of the periodic table. Dull appearance
Poor conductors of heat & electricity
Brittle (break easily)
Solids or gases

5. Metalloids Found between metals and non-metals in a stair step line.
Elements that have characteristics of both metals and nonmetals.
Specific characteristics depend on the element.
All solids, can be shiny or dull, they are conductors but not as good as metals (semi-conductors).
Boron
Silicon
Germanium
Arsenic
Antimony
Tellurium
Polonium
Astatine

6. Noble Gases The far right column (group 18) on the periodic table.
Sometimes considered to be non-metals, but often an independent group because they do NOT react with other elements
Very stable and non-reactive elements.
All gases
