1

matter

anything that takes up space and has mass

New cards
2

mass

the measure of the amount of matter

New cards
3

weight

New cards
4

atom

the smallest unit of an element that maintains the chemical identity of that element

New cards
5

element

a pure substance that cannot be broken down into simpler stable substances (one kind of atom)

New cards
6

compound

a pure substance that can be chemically broken down into simpler, stable, substances (made of atoms of 2 or more elements that combine chemically)

New cards
7

properties

characteristics that allows us to distinguish one kind of matter from another (2 kinds; extensive & intensive)

New cards
8

extensive

depends on the amount of matter present (volume, length, mass, etc.)

New cards
9

intensive

does not depend on the amount present (boiling point, melting point, density, etc.)

New cards
10

physical property

a characteristic that can be observed or measured without changing its' identity (boiling, melting, etc.)

New cards
11

physical change

any change in property that does not change its' identity (phase changes, etc.)

New cards
12

chemical property

a substance's ability to undergo changes that transforms it into different substances (burn, rust, tarnish, etc.)

New cards
13

chemical change/reaction

a change in which 1 or more substances are converted to other substances

New cards
14

pure substance

the composition is the same throughout; cannot be separated by physical means (elements & compounds)

New cards
15

mixture

a combination of 2 or more substances where each retain its identity & properties; can be separated by physical means (2 types)

New cards
16

heterogenous

composition & properties are not uniform throughout

New cards
17

homogenous

composition & properties are uniform throughout

New cards
18

homogenous
