Front 2

Pure substance

Back 2

is a substance in which there is only one type of particle

Front 3

Metals

Back 3

are elements that are shiny, good conductors of thermal energy and electric currents, and are malleable

Front 4

Nonmetals

Back 4

are elements that are dull and are poor conductors of thermal energy and eletric currents

Front 5

Metalloids

Back 5

are elements that have propertes of nonmetal and metal, some are shiny and some are dull, are somewhat malleable and ductile

Front 6

Compound

Back 6

is a pure substance composed of two or more elements that are chemically combined

Front 7

Mixture

Back 7

is a combination of two or more substances that are not chemically combined

Front 8

Front 9

Solute

Back 9

is the substance that is dissolved

Front 10

Solvent

Back 10

is the substance in which the solute is disolved

Concentration

Back 11

can be expressed in grams of solute per mililiter of solvent

Front 12

Solubility

Back 12

of a solute is the amount of solute needed to make a saturated solution

Front 13

Suspension

Back 13

is a mixture in which particles of a material are dispersed throughout a liquid or gas

Front 14

Colloid

Back 14

is a mixture in which the particles are dispersed throughout but are not heavy enough to settle down
