4Physical vs. Chemical Change Changing from one state to another is aPhysical Change.If a new substance is formed it is aChemical Change.Images are from
5Atoms Elements The building blocks of Matter Consists of Protons (+), Electrons (-),and Neutrons (N).ElementsConsists of only one kind of atom,Cannot be broken down into a simpler type of matter by either physical or chemical meansCan exist as either atoms or molecules.Images are from
6MoleculesA molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.In the animation above, two nitrogen atoms(N + N = N2) make one Nitrogen molecule .
7Compounds Atoms of two or more different elements bound together. Can be separated into elements chemically, but not physically.In the animation above, water (H20) is a compound made of Hydrogen and Oxygen.Animated images and notes from
8Solutions Homogeneous Solutions are groups of molecules that are mixed up in a completely even distribution.HomogeneousUniform Distribution.Example: Sugar and WaterImages are from
9Solute Solvent The substance to be dissolved. The one doing the dissolving.Images are from
11ColloidsParticle sizes are in between the size of particles found in solutions and suspensions .Can be mixed and remain evenly distributed without settling out.
12Mixtures Heterogeneous They are substances held together by physical forces, not chemical.Can be separated physically.Solutions are also mixtures.HeterogeneousThe substances are not uniformly mixed.Example: Sand in a glass of water.Images are from
13Mixtures Suspensions Are heterogeneous mixtures consisting of parts that are visible to the naked eye.Substances will settle over time.Example: the ingredients in salad dressing
