MATTER Pure Substances Mixtures ElementsCompoundsHeterogeneousHomogeneous Particle:AtomEx: O, H, Na, C Particle:MoleculeEx: H 2 O, NaCl, CO 2 Parts not visible, evenly mixed Ex: Salt water, air,coffee Visibly different parts Ex: Salt + pepper, Water + sand

PURE SUBSTANCES t ★ Single kind of matter ★ Specific composition ★ Specific Properties ★ Elements and Compounds ★ Examples: Gold CO 2 Water

ELEMENTS ★ Most basic form of matter ★ Cannot be seperated or broken down ★ 116 elements in the Periodic Table ★ Represented by symbols O, H, Fe, Au, He, Ne, C ★ Smallest particle - atom

Carbon (Coal and diamonds) Mercury Examples Oxygen

Compounds ★ 2 or more elements chemically combined in a set ratio ★ Can only be separated by chemical methods electrolysis of waterelectrolysis of water ★ Represented by a formula ★ Smallest particle- molecule

Examples water salt (sodium chloride) ammonia (NH 4 ) rust (iron oxide) chalk (calcium carbonate) sugar (glucose)

MIXTURES ★ 2 or more substances, combined, but NOT chemically ★ Can be separated by physical means

Homogeneous mixtures ★ Evenly distributed particles ★ Particles NOT visible ★ The prefix: "homo"- indicates the same ★ Have the same uniform appearance and composition throughout Examples: Air Solutions (salt water) Alloys

Heterogeneous mixtures ★ Visibly different parts ★ The prefix: "hetero"- indicates difference Examples: Salt and pepper Sulfur and iron Soup Rice Pizza
