1. Any pure substance that can’t be broken down into any simpler substance by some physical or chemical
method and from which all more complex forms of matter are made when they are combined together in
different ways and in different amounts is called a(n) ELEMENT

Elements, Mixtures and Compounds Crossword Puzzle, P. 9
2. The smallest particle of any element you can have which still possesses all of the physical and chemical
properties of that element is called a(n) ATOM of that element.

3. At the present time 118
232-233
different elements have been discovered and officially recognized and named. PP
4. The unique single letter (Hydrogen – H), two letter (Helium – He) or three letter (Unnilquadiam – Unq)
abbreviation for each element that was created by JONS BERZELIUS is called the CHEMICAL
SYMBOL of that element. Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword
Puzzle, P. 83
5. A complex form of matter which is composed of a combination of two or more different substances whose
physical and chemical properties don’t change after they have been combined together is called a(n)
MIXTURE. Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P. 12
6. Since the substances which were combined together to form a mixture have not changed and have not been
bonded together during a chemical reaction to form a new substance they can easily be SEPARATED
APART by some simple physical or mechanical method of separation.
Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P. 13
7. If the substances that are combined together to form a mixture are not evenly mixed, distributed or dispersed
throughout the mixture then it is called a(n) HETEROGENEOUS mixture.
Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P. 12
8. If the substances that are combined together to form a mixture are evenly mixed, distributed and dispersed
throughout the mixture then it is called a(n) HOMOGENEOUS
mixture.

A.
SUSPENSION
B.
COLLOID
C.
SOLUTION
11. A(n) SUSPENSION is a type of heterogeneous liquid mixture in which the substance that you are
combining with a liquid separates out and rapidly settles to the bottom of the container.

and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P. 201
12. Some examples of different types of suspensions.

A. SAND IN WATER
B. GRAVEL IN WATER
C. MUDDY WATER
13. A(n) COLLOID is a type of homogeneous liquid mixture in which the particles of the solid that are
mixed in a liquid are visible because they do not completely dissolve in the liquid and they may or may not
separate out and settle to the bottom of the container very slowly over a period of time. Video: Mixtures and
Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P. 201
14. Some examples of different types of colloids.

A. KETCHUP AND MUSTARD
B. PAINT
C. SOUR CREAM AND CHIP DIP
15. A type of homogeneous liquid mixture in which the substance that you are combining with a liquid never
separates out and settles to the bottom of the container is called a(n) SOLUTION
Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P. 199
16. The two part of a solution are the SOLUTE and SOLVENT.
Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P.P. 199 - 200
17. The solid, liquid or gas which is being dissolved in a liquid is called the SOLUTE in a solution. Video:
Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P.P. 199 - 200
18. The liquid which you’re dissolving a solid, liquid or gas in, is called the SOLVENT in a solution.
Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P.P. 199 - 200
19. If you dissolved salt in water to form a solution the SALT would be the solute and the WATER would
be the solvent in this solution. Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword
Puzzle, P.P. 199 - 200
20. WATER is sometimes called the “Universal Solvent” because it is the most common solvent used in the
formation of a solution. Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword
Puzzle, P. 199
21. Some examples of different types of solutions are: Video: Mixtures and Solutions, Elements, Mixtures and
Compounds Crossword Puzzle, P.P. 199 - 200
A.
SALT OR SUGAR DISSOLVED IN WATER
(solid solute dissolved in a liquid solvent)
B.
ANTIFREEZE DISSOLVED IN WATER
(liquid solute dissolved in a liquid solvent)
C.
OXYGEN DISSOLVED IN WATER
(gas solute dissolved in a liquid solvent)
22. The abbreviation for the word solution is SOLN.
Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle
23. A measurement of the rate at which a substance (solid, liquid or gas) can be dissolved in a liquid is called
the SOLUBILITY of that substance in that liquid. Video: Mixtures and Solutions, Elements, Mixtures and
Compounds Crossword Puzzle, P. 207
24. If you can dissolve a substance (solid, liquid or gas) in a liquid then we say that it is SOLUBLE in that
liquid. (Example: Salt in Water)
Video: Mixtures and Solutions, Elements, Mixtures and Compounds
Crossword Puzzle
25. If a substance (solid, liquid or gas) can’t be dissolved in a liquid then we say that it is INSOLUBLE
that liquid. (Example: Oil in Water)

Compounds Crossword Puzzle
in
26. If you increase the speed that you stir a substance (solid, liquid or gas)in a liquid, increase pressure, increase
the temperature of the liquid, or decrease the size of the solid particles that you are dissolving in a liquid then
you will INCREASE the speed that it will dissolve in that liquid. Video: Mixtures and Solutions,
Elements, Mixtures and Compounds Crossword Puzzle, P.P. 208 - 209
27. A solution can be UNSATURATED, SATURATED or SUPERSATURATED with the solute.
Video: Mixtures and Solutions, Elements, Mixtures and Compounds Crossword Puzzle, P.P. 207, 209
28. If more solute (salt, sugar, etc) can be dissolved in a solvent (water) at room temperature then the solution is
called a(n) UNSATURATED solution. Video: Mixtures and Solutions, Elements, Mixtures and
Compounds Crossword Puzzle, P. 207
29. If no more solute (salt, sugar, etc) can be dissolved in a solvent (water) at room temperature then the solution
is called a(n) SATURATED solution. Video: Mixtures and Solutions, Elements, Mixtures and Compounds
Crossword Puzzle, P. 207
30. If no more solute (salt, sugar, etc) can be dissolved in a solvent (water) at the boiling point of the solution
then it is called a(n) SUPERSATURATED solution. Video: Mixtures and Solutions, Elements, Mixtures
and Compounds Crossword Puzzle, P. 209
31. As the concentration of the solute (salt, antifreeze, etc.) dissolved in the solvent increases the normal boiling
point of the solvent will be INCREASED while the normal freezing point of the solvent will be
DECREASED.
