Matter • Anything that has a mass and a volume

• The building blocks of Matter • Consists of Protons (+), Electrons (-), and Neutrons (N). • Consists of only one kind of atom, • Cannot be broken down into a simpler type of matter by either physical or chemical means • Can exist as either atoms or molecules.

• A molecule consists of two or more atoms of the same element, It is a Pure Substance…. • In the animation above, two nitrogen atoms (N + N = N 2) make one Nitrogen molecule.

• Atoms of two or more different elements bound together. • Can be separated into elements chemically, but not physically. In the animation above, water (H 20) is a compound made of Hydrogen and Oxygen. Animated images and notes from http: //www. chem. purdue. edu/gchelp/atoms/elements. html

• Solutions are groups of molecules that are mixed up in a completely even distribution. Images are from http: //www. chem 4 kids. com

• The substance to be dissolved. • The one doing the dissolving. Images are from http: //www. chem 4 kids. com

• They are substances held together by physical forces, not chemical. • Can be separated physically. • Solutions are also mixtures. Images are from http: //www. chem 4 kids. com

• mixtures consisting of parts that are visible to the naked eye. • Substances will settle over time. Example: the ingredients in salad dressing

Discussion • Describe the movement of particles in a solid and the forces between them. ▫ Solid particles vibrate in place and they have strong attractive forces between the particles. • How do particles move and interact in a gas? ▫ Gas particles move freely, spread out, and they have little attraction for other gas particles.

Challenge • How is temperature related to particle motion? ▫ Temperature is directly related to particle motion. The higher the temperature, the more kinetic energy the particles have. The more kinetic energy particles have, the faster they move.
