Physical Properties | One which you can observe without changing the substance. |
State: Solid | Has a definite shape and volume. Atoms tightly packed. |
State: Liquid | Has a definite volume but indefinite shape. Atoms spread out a little. |
State: Gas | Has neither a definite shape nor volume. Atoms spread everywhere. |
Chemical Properties | Relates to a substances ability to undergo changes that transforms it into different substances. -Flammability -Whether it reacts with oxygen or not -How it reacts when combined with other compounds |
Mixtures | A blend of two or more kinds of matter; each retains its own properties. |
Homogeneous Mixture | Solution |
Heterogeneous Mixture | Not uniform throughout. |
Pure Substances | Has a fixed composition. |
Periodic Table | Table that organizes all known elements. |
Groups/Families | Vertical columns that have similar chemical properties. |
Periods | Horizontal row. Physical and chemical properties change somewhat regularly across a period. |
Metals | -Good conductors of heat and electricity. -Solid- many are malleable and ductile -Most have a luster |
Nonmetals | -Not good conductors -Tend to be brittle -Gases at room temperature |
Metalloids | -Solids at room temperature -Tend to be semiconductors or electricity |
