Matter

.Anything that has mass and takes up space

1

Mass

.Measure of the amount of matter in an object

2

Volume

.Describes how much space a piece of matter takes up

3

Atom

.Smallest particle or part of matter

4

Molecule

.Two or more atoms joined together

5

Nucleus

Middle of atom containing protons and neutrons

6

Liquid

.Liquids have indefinite shape and definite volume, tightly packed but far enough apart to slide over one another

7

Gas

.Indefinite shape and volume, part les far apart and move freely

8

Plasma

.Particles that move freely, don't have a shape and are electrically charged

9

Element

.Matter that is made up of only one kind of atom

10

Proton

11

Neutron

Neutrally or not charged practical in atomic nucleus.

12

Electron

Negatively charged part of the atom surrounding the atomic nucleus

13

Element

.Matter that is made of only one kind of atom

14

Atomic number

.Number of protons in nucleus

15

Density

.Tells how massive something is for it's size

16

Buoyancy

.An object's ability to float

17

19

Physical reaction

.Type of change from one form to another (water to ice)

20

Conservation of matter

.Chemical changes don't make new matter

21
