Elements
Are a pure substance
Can NOT be broken into a simpler
substance physically or chemically

Pure substances
Have only one type of particle
Particles are called atoms
All atoms are EXACTLY the same

Characteristic Properties
Characteristics do not depend on the
amount of the element
Physical characteristics:
Boiling point, melting point, density,
etc
Chemical characteristics:
Reactivity with acid, flammability, etc.

Identifying Elements
Elements are unique
May share some properties with other
elements, but not ALL properties

Metals
Shiny
Conduct heat energy
Conduct electric current
Ex: iron, nickel, cobalt

Nonmetals
Do not conduct heat energy
Do not conduct electric current
Solid nonmetals are dull looking
Ex: iodine, sulfur, neon

Metalloids
Have properties of both metals and
nonmetals
Ex: silicon, boron, antimony
