Elements, Compounds and Mixtures Google Slides Notes

Matter is anything that has mass and volume.

Remember…

Massis a measure of how
much matter is in an object.

Volumeis the amount of

space taken up by an object.

Some types of matter are substances and some are

not.

A substance is a single kind of matter that is pure,

meaning it is made up of only one type of atom or

molecule.

atom
molecul

es

An atom is the basic particle from which

all elements are made.

A molecule is a group of 2 or more atoms

held together by chemical bonds.

An element is a substance that cannot be broken

down into any other substances by chemical or

physical means.

The Element Song

Most elements are
made up of the same

individual atoms.

Some elements (7) are

diatomic molecules, which
means they have 2 atoms

bonded together.

A compound is a substance made of 2

or more elements that are chemically

combined in a set ratio.

A mixture is made of 2 or more substances

that are together in the same place, but
their atoms are not chemically bonded.

Mixtures can be

homogeneous or heterogeneous

A homogeneous mixture has substances that

are so evenly mixed that you can’t see the

different parts.

milk

soy sauce

Kool-Aid

coffee

vinegar

dish soap

A heterogeneous mixture is made up of
particles that you can usually see and they

can easily be separated.

guacamole

M & M’s

trail mix

salad

pizza

cereal

When you receive a lab paper, read through

the directions and the chart on the front

page.

Then answer the 5 pre-lab
questions and be ready for

further instructions.

A mixture is classified as a solution, colloid, or

suspension based on the size of its

particles.

solution
colloid

n

smallest

largest

A solution is a mixture containing a solvent and at

least one solute and it has the same properties

throughout.

Solute: the substance being dissolved

Solvent: the substance that is usually present in the

largest amount & does the dissolving

For each of the following solutions, determine

what the solutes and solvents are.

In many of the solutions on the previous

slide, water is the solvent.

Since water dissolves so many substances,

it is often called the “universal solvent.”

dilute

concentrated

saturated

A solution can be described in terms of the

amount of solute dissolved in a given amount of

solvent.

Dilute: only a little solute is dissolved

Concentrated:a lot of solute is dissolved

Saturated: so much solute has been added that no

more can dissolve

A colloid is a mixture containing small, undissolved

particles that do not settle out.

The particles are too small to be seen without a

microscope, yet they are large enough to scatter a beam

of light.

A suspension is a mixture in which particles

can be seen and easily separated by

settling or filtration.

snow globe

muddy water

Filtration – this a good method for
separating an insoluble solid (one that
does not dissolve) from a liquid; they
separate when pouring the mixture

through a filter

Evaporation – this is good for separating a

soluble solid (one that dissolves) from a
liquid; the liquid changes to a gas & the

solid components are left behind

Distillation – good for separating liquids

from each other

Magnetic attraction – good for separating

iron from a mixture

Find the domino with this on it & lay it down first.

Read the definition & look for the vocabulary term on another

domino. When you find it, lay it down next to the definition
(like you would do with dominoes). Repeat until all of the

dominoes have been used.

If you’ve matched all of the terms and definitions correctly, the

domino with this on it should be the last one you lay down.
