Term | Answer |
Matter | anything that has mass and takes up space |
Physical Change | does not alter the chemical makeup of a substance (breaking, mp, bp, fp) |
Chemical Property | the ability of a substance to change into a different substance |
Chemical Change | alters the chemical makeup of a substance (digestion, growth, burning or rotting of food). Involves a chemical reaction |
States of Matter | Solid: has a defined shape and volume independent of its container. Liquid: has a defined volume but a variable shape that depends on its container. Gas: no defined shape or volume, has a variable shape and volume that depends on its container. |
Intensive Properties | do not depend on the amount of the substance (melting pt., boiling pt., density) |
Pure | can be either an element (Oxygen, Sulfur) like pure metals (Gold) or a compound like salt or water. always the same composition and properties |
Mixture | can be homogeneous (same throughout, one phase) or heterogeneous (not the same throughout, many phases) (seawater, mayo, rocks) |
Extensive Properties | dependent on the amount of a substance (mass and volume) |
Atomic Mass | sum of the # of protons and neutrons in an element |
Atomic Number | the # of protons in an element |
Metal | solid at room temp., have a lustrous appearance, are good conductors of heat and electricity and are malleable |
Nonmetal | brittle nature, nonconductors of heat and electricity |
metalloids | elements that have properties similar to both metals and nonmetals |
physical property | any aspect of an object or substance that can be measured or perceived without changing its identity (melting point, boiling point, density) |
