3. TermDefinition Chemistry Matter Physical change Chemical change Qualitative The study of matter and its properties Anything that has mass and takes up space A change that does not involve the formation of a new substance. Ex: change of state or form A change that involves the creation of a new substance. Ex: burning, any chemical reaction An observation that involves a quality of a substance (no numbers)

4. TermDefinition Quantitative Mixture Solution (homogenous) Heterogeneou s Mixture Pure Substance An observation that involves a measured quantity (numbers) A sample containing more than one distinct substance A mixture that consists of one phase (ex: salt water). A mixture that contains more than one phase (ex: oil and water) A sample that contains one chemical substance (can be either an element or compound)

5. TermDefinition Element Compound Atomic Number Mass number A pure substance consisting of atoms that are all from the same element on the periodic table. A pure substance containing atoms from more than one element, bonded together chemically. Represents the number of protons in one atom of an element. Represents the mass of one atom of an element (number of protons + number of neutrons)
