MATTER Pure Substances Mixtures Elements Compounds Homogeneous Heterogeneous Particle: Atom Ex: O, H, Na, C Parts not visible, evenly mixed Ex: Salt water, air,coffee Visibly different parts Ex: Salt + pepper, Water + sand Particle: Molecule Ex: H2O, NaCl, CO2
MATTER Anything that has mass and takes up space Unit gram (g) Unit cm3 1 cm3 = 1 ml
Elements and Compounds Examples: PURE SUBSTANCES Single kind of matter Specific composition Specific Properties Elements and Compounds Examples: CO2 Water Gold
ELEMENTS Most basic form of matter Cannot be seperated or broken down 116 elements in the Periodic Table http://www.chemicool.com Represented by symbols O, H, Fe, Au, He, Ne, C Smallest particle - atom
Carbon (Coal and diamonds) Examples Carbon (Coal and diamonds) Mercury Oxygen
Compounds 2 or more elements chemically combined in a set ratio Can only be separated by chemical methods electrolysis of water Represented by a formula Smallest particle- molecule
Examples water salt (sodium chloride) ammonia (NH4) rust (iron oxide) chalk (calcium carbonate) sugar (glucose)
MIXTURES 2 or more substances, combined, but NOT chemically Can be separated by physical means
Air Solutions (salt water) Alloys 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 Rice Soup Pizza Sulfur and iron
