Matter

Front 1

This number is how many different kinds of atoms make up an element.

Back 1

One

Front 2

A group of symbols and numbers that shows what elements make up a compound.

Back 2

Chemical Formula

Front 3

H2SO4

Back 3

2 hydrogen atoms, 1 sulfur atom, 4 oxygen atoms

Front 4

These are the properties of metals.

Back 4

Usually shiny, can be formed into sheets and wire and are good conductors of heat and electricity.

Front 5

This part of a solution makes up the smallest part.

Back 5

Solute

Front 6

The four groups all elements are sorted into.

Back 6

Metals, nonmetals, semimetals, noble gases.

Front 7

These particles of an atom swarm around the nucleus like a swarm of bees.

Back 7

Electrons

Front 8

One or two letters used to stand for the name of an element.

Back 8

Chemical Symbol

Front 9

A substance that cannot be broken down into any other substance by ordinary chemical means is this.

Back 9

element

Front 10

This is one way that compounds and mixtures are alike.

Back 10

They are both made up of different kinds of matter.

Front 11

These two particles are located in the center or nucleus of an atom.

Back 11

Protons and neutrons

Front 12

This is one way atoms can be joined together to form a compound.

Back 12

Two different kinds of atoms may share electrons.

Front 13

This is one way atoms may be joined together to form a compound.

Back 13

A positively charged atom and a negatively charged atom are attracted to each other and become chemically bonded.

Front 14

This part of an atom has a neutral charge.

Back 14

Neutron

Front 15

This is the center of an atom.

Back 15

Nucleus

Front 16

This part of a solution is the largest part.

Back 16

Solvent

Front 17

This describes how many different kinds of atoms make up a compound.

Back 17

Two or more

Front 18

A substance made up of two or more elements that are chemically combined.

Back 18

Compound

Front 19

This is one way that compound and mixtures are different.

Back 19

The parts of a mixture can be physically separated; a compound cannot.

Front 20

a mixture in which the different particles or kinds of matter are spread evenly throughout the mixture.

Back 20

Mixture

Front 21

This part of an atom has a positive electrical charge.

Back 21

Proton

Front 22

These are examples of mixtures.

Back 22

glass, air, brick, cement, asphalt, blood sweat, tears, saliva

Front 23

This is a particle made up of a group of atoms that are chemically bonded, or joined.

Back 23

Molecule

Front 24

This is one way that compounds and mixtures are different.

Back 24

The parts that make up a compound lose their original properties; the parts that make up a mixture keep their original properties.

Front 25

This is a way that compounds and mixtures are different.

Back 25

A compound can be written as a chemical formula; a mixture cannot.

Front 26

This part of an atom has a negative electrical charge.

Back 26

Electron

Front 27

This is a liquid mixture is which some particles are temorarily suspended in the mixture. Example salad dressing
