| study of the properties and changes of matter and their relation to energy | Physical Chemistry |
| identification of components and composition of materials | Analytical Chemistry |
| chemistry of living things | Biochemistry |
| use of math and computers to understand the principles behind observed chemical behavior | Theoretical Chemistry |
| doing research for the sake of gaining knowledge | Basic Research |
| generally carried out to solve a problem | Applied Research |
| involves the production of products that improve our way of life | Technological Development |
| anything that has mass and volume | Matter |
| measure of the amount of matter | Mass |
| how much space something takes up | Volume |
| smallest unit of and element | Atom |
| pure substance made of only one kind of atom | Element |
| made of 2 or more kinds of atoms chemically bound together | Compound |
| depends upon the amount of matter present | Extensive Properties |
| do not depend on the amount of matter present | Intensive Properties |
| one which you can observe without changing the substance | Physical Properties |
| has a definite shape and volume | Solid |
| has a definite volume but and indefinite shape | Liquid |
| Has neither a definite shape or volume | Gas |
| high temperature physical state of matter in which atoms loses their electrons | Plasma |
| relates to a substances ability to undergo changes that transforms it into different substances | Chemical Properties |
| a blend of 2 or more kinds of matter; each retains its own properties | Mixture |
| solution like saltwater, tea | Homogeneous Mixture |
| not uniform throughout like sand and water, oil and water, wood, blood | Heterogeneous Mixture |
| has a fixed composition | Pure Substance |
| table that organizes all known elements | Periodic Table |
| vertical columns that have similar chemical properties and have the same number of valence electrons | Groups or Family |
| horizontal rows. physical and chemical properties change somewhat regularly across a period and same energy levels | Periods |
| good conductors of heat and electricity solid- many are malleable( pound into different shapes) and ductile (can be drawn out into a wire) most metals have a luster (shiny or a silvery grayish appearance) | Metal |
| not good conductors tend to be brittle gases (mostly) at room temperature | Nonmetal |
| have some characteristics of metals and some of nonmetals solids at room temperature tend to be semiconductors of electricity | Metalloids |
| group 18 and nonreactive and many times are used in lighting | Noble Gases |
| is used to measure liquids | Graduated Cylinder |
