This document defines and provides examples of elements, compounds, mixtures, homogeneous mixtures, and heterogeneous mixtures. An element is made of a single type of atom, while a compound is made of two or more different types of atoms chemically bonded together. A mixture does not form new chemical bonds between its components. Homogeneous mixtures are uniform throughout, while heterogeneous mixtures are not uniform and can be seen as distinct layers or parts. Examples include aluminum foil as an element, salt as a compound of sodium and chlorine, lemonade as a mixture, milk as a homogeneous mixture, and pizza as a heterogeneous mixture.

1. Example of an Element
● This aluminum foil
is an element
because it is made
of the element
aluminum.

2. Example of a Compound
● Salt is a compound
because it is made
up of more than
one atom.
● Salt is made out of
two elements which
are sodium and
chlorine. (NaCl)

3. Compound
● Water is a
compound because
it is made up of two
elements which are
hydrogen and
oxygen. (H2O)

4. Example of a Mixture
● Lemonade is a
mixture because it
was mixed with
lemon, water, and
sugar.
● A mixture is two
properties
combining without a
new chemical
forming.

5. Mixture
● Salt water is a
mixture because
water and salt are
mixed in and there
aren't any new
chemicals.

6. Mixture
● Sugar water is also a
mixture because it is
made up of only
sugar and water.

7. Example of a Homogenous mixture
 This glass of milk is
an example of a
homogenous mix-
ture because it is
the same from top
and bottom.

8. Homogenous mixture
 Lotion is a homo-
genous mixture be-
cause there are no
layers or different
parts of this mix-
ture.

9. Example of a Heterogeneous Mixture
● This cereal is a
heterogeneous mixture
because it has many
layers of cereal and
milk.

10. Heterogeneous Mixture
● This pizza is a
heterogeneous mixture
because this has many
layers of pepperoni,
cheese, sauce, and the
crust.
