Matter
2
Matter Anything that has a mass and a volume
3
Atoms Elements The building blocks of Matter
Consists of Protons (+), Electrons (-), and Neutrons (N). Elements 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. Images are from
4
Molecules A 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 .
5
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
6
Solutions Homogeneous
Solutions are groups of molecules that are mixed up in a completely even distribution. Homogeneous Uniform Distribution. Example: Sugar and Water Images are from
7
Making a Solution
8
Colloids Particle sizes are in between the size of particles found in solutions and suspensions . Can be mixed and remain evenly distributed without settling out.
9
Mixtures Heterogeneous
They are substances held together by physical forces, not chemical. Can be separated physically. Solutions are also mixtures. Heterogeneous The substances are not uniformly mixed. Example: Sand in a glass of water. Images are from
10
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
