Front 1

abundant

Back 1

occuring most often

Front 2

atom

Back 2

the smallest unit of an element that retains the properties of the element.

Front 3

capillary action

Back 3

The spontaneous movement of water into thin tubes or fibers, caused by the polar properties of water.

Back 4

the electrical force linking atoms

Front 5

chemical equation

Back 5

a shorter, easier way to show chemical reactions, using symbols instead of words

Front 6

chemical formulas

Back 6

equations that show the number and connections of atoms in compounds and chemical reactions

Front 7

chemical property

Back 7

a characteristic of a substance that is observed when a substance interacts with another substance

Front 8

chemical reaction

Back 8

the breaking or formation of chemical bonds (producing new material and/or changing the amount of energy)

Front 9

chemical symbols

Back 9

universally recognized abbreviations for chemical elements in which the first letter is always capitalized

Front 10

chemistry

Back 10

the study of the properties of matter and how matter changes

Front 11

compound

Back 11

a substance in which two or more elements are chemically bonded, and which has a chemical formula

Front 12

coefficient

Back 12

the large number to the left of the chemical symbol that indicates the number of molecules

Front 13

cohesion

Back 13

the force of attraction between similar molecules

Front 14

electrons

Back 14

negatively charged particles that orbit the nucleus of an atom

Front 15

element

Back 15

a substance composed of a single kind of atom which is listed in the periodic table

Front 16

energy

Back 16

the ability to do work or cause change

Front 17

matter

Back 17

everything that has mass and volume is made of this

Front 18

mixture

Back 18

made from two or more substances that are not chemically bonded. Most matter is found in this form.

Front 19

molecule

Back 19

a particle of matter made up of 2 or more atoms bonded together.

Front 20

neutron

Back 20

small, uncharged particle in the nucleus of an atom

Front 21

nucleus

Back 21

center of an atom consisting of protons and neutrons

Front 22

periodic table

Back 22

the chart of all of the elements

Front 23

physical property

Back 23

a characteristic of a substance that can be observed without changing the substance

Front 24

polar

Back 24

having a pair of opposite charges

Front 25

protons

Back 25

small, positively (+) charged particles in the nucleus of an atom.

Front 26

solute

Back 26

the substance dissolved in the solvent. In Kool-Ade, the flavored mix is this.

Front 27

solution

Back 27

a mixture in which one substance is dissolved in another.

Front 28

solvent

Back 28

a substance in which another substance is dissolved, forming a solution. In Kool-Ade, the water is this.

Front 29

states of matter

Back 29

solid, liquid & gas

Front 30

sub-atomic particles

Back 30

an elementary part of the atom: proton, neutron, or electron

Front 31

subscript

Back 31

the small number to the right of an element symbol that indicates the number of atoms

Front 32

substance

Back 32

A single kind of matter that has distinct physical and chemical properties

Front 33

surface tension

Back 33

the tightness across the surface of water caused by polar water molecules pulling on each other. This allows some insects to walk on the surface of water without sinking

Front 34

universal solvent

Back 34

a substance that has the ability to dissolve both bases and acids. Water dissolves more substances than any other liquid.
