3 States of Matter Solid Liquid Gas Plasma Close up view of atoms and their behaviorAnimated images are from
4 Physical 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
5 Atoms 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
6 MoleculesA 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 .
7 Compounds 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
8 Solutions Homogeneous Solutions are groups of molecules that are mixed up in a completely even distribution.HomogeneousUniform Distribution.Example: Sugar and WaterImages are from
9 Solute Solvent The substance to be dissolved. The one doing the dissolving.Images are from
11 ColloidsParticle sizes are in between the size of particles found in solutions and suspensions .Can be mixed and remain evenly distributed without settling out.
12 Mixtures 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
13 Mixtures 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
