1. Chemistry: Elements Chapter 5

2. Elements
Elements- Substances that cannot be broken down into a simpler substance.
Remember that elements are only made of atoms of that element! (The element iron is made of only iron atoms)
Elements are the building blocks of all other substances.

3. Elements and states of matter
Elements can be solids, liquids, or gases
Examples Solids Elements Liquid Elements Gas Elements
Hydrogen
Oxygen
Nitrogen
Helium
Gold
Carbon
Iron
Sulfur
Copper
Magnesium
Mercury
Bromine

4. Elements and states of matter
Most elements are solids at ordinary temperatures. Some elements are gases. Only two elements are liquids at room temperature.
Each element has its own special properties that help identify it

5. Elements and substances
Some substances are composed of only one element
Iron Nails
Aluminum Foil
Copper Wire
Tin Can
Some substances contain more than one element
Water
Salt
Sugar
Steel
Brass

6. Metals Metals have these properties Examples of Metals
Have a bright and shiny luster
Are malleable
Most are silver-gray in color
Most are solids (Except mercury)
Are good conductors of electricity
Are good conductors of heat
Examples of Metals
Aluminum, Tin, Lead, Iron, Gold, Copper, Nickel, Mercury

7. Non-Metals Non-Metals have these properties Examples of Non-Metals
Solids, Liquids, or gases
Dull Luster
Different Colors
Poor conductors of electricity
Poor conductors of heat
Examples of Non-Metals
Hydrogen, Oxygen, Sulfur, Bromine, Krypton, Carbon

8. Metalloid
Metalloids share some properties with metals and some with non-metals
Examples of Metalloids
Boron, Silicon, Arsenic, Antimony
