Molecule = 2 or more atoms bonded
(can be the same element or different
elements)
 Compound = 2 or more different
elements bonded
 Mixture = 2 or more substances
combined
 Solution = A type of mixture that looks
the same throughout


Pure substances made of only one type of
atom
MUST be on the Periodic Table OF ELEMENTS
Combine to form all other types of matter

Examples:


 Silver
 Calcium
 Oxygen

Atoms of one
element

Molecules of the
one element

Two or more different elements bonded
during a chemical reaction = CHEMICAL
CHANGE
Must be combined in specific ratios

Examples:

 Water (H2O)
 Salt (NaCl)
 Sugar (C6H12O6)

What do you notice about a
compound’s chemical structure?
What is
evidence that
a chemical
reaction is
happening
again?

Combines 2 or more substances without
producing a chemical reaction = PHYSICAL
CHANGE

HETEROGENEOUS = Different throughout

Basic mixtures can be separated easily

Examples:
 Soil
 Fruit salad
 Trail mix

What do you notice about how a mixture
looks chemically?






A type of mixture that is the same throughout = STILL
A PHYSICAL CHANGE
HOMOGENEOUS – same throughout
Can be solids, liquids or gases
Solute- substance being dissolved
Solvent- substance doing the dissolving
Examples:
 Salt water
 Lemonade
Salt =
Solute
CAN YOU
SEPARATE A
SOLUTION?
Water=
Solvent
Salt Water=
Solution

It is also a mixture of 2 or more SUBSTANCES,
but the separate substances will NOT be
visible because they are evenly mixed!
Read the “Elements, Compounds,
Mixtures, & Solutions article, and use
it to answer the questions.
 Preview the questions so you know
what you are reading for…highlight,
underline, annotate, use sign posts…

 When
you complete the questions
please have me check them
before you move to the stations!
 Visit
each station and describe
what you see using information
from the article, notes and
previous activities…I want
scientific explanations – that
means use vocabulary!!
 Each station has many
explanations…ticket time!!
 Raise
your hand and state ONE
correct scientific description.
 Must be correct to get a
ticket…NO REPEATS, so pay
attention!
 YOUR GOAL: Get at least 1 ticket
to be in the drawing!
 ADOPT-AN-ELEMENT
BABY BOOK
DUE NEXT CLASS…BE SURE TO
HAVE A HARD COPY WITH YOU!
 Elements,

HOMEWORK: Chemistry Test 2 Study Guide
15
You will complete this investigation with your lab
group.
1. Read the introductory information and answer the
questions together – COMPLETE THE FIRST 4
QUESTIONS AND THEN STOP
2. ECMS KAHOOT while we wait for the results, so
get logged in once your cup is set up
3. Analyze the results and complete the back of the
sheet
Clean-Up:
1. Throw your paper strip in the
garbage.
2. Dump the water into your sink.
3. Bring your EMPTY cup & stick
back to the counter.
4. Make sure the graduated cylinder
is next to the sink where you
found it.


I will show you a picture and you need to determine what
category it falls into and write it on your whiteboard.
Your answer choices will be one of the following:
 Element = E
 Compound = C
 Mixture = M
 Solution = S
There are 4 rounds with 5 questions each – each
round you have a chance for a ticket!
◦ 1st & 2nd round = 1 wrong for a ticket
◦ 3rd, 4th = 100% for a ticket
YOU CAN GET ONE WRONG
AND STILL GET A TICKET…

Which subatomic particle is involved in
bonding? Be specific…

Find the number of valence electrons
for each of the elements below:
◦ Radium
◦ Antimony
◦ Polonium
◦ Rubidium

Atoms give away or steal valence electrons
in order to happy and stable with a full
valence shell!
◦ Atoms with less than 4 valence electrons
tend to lose electrons – “Givers”
◦ Atoms with more than 4 valence electrons
tend to gain electrons – “Stealers”
 Ionic
◦ Metal & Nonmetal
◦ Transfer/Take
electrons
◦ Salt (NaCl)
 Covalent
◦ 2 non-metals
◦ Share
electrons
◦ Water (H2O)
Bonding is a Chemical Change, SO…
 Molecules = Chemical Change – 2 or more
atoms bonded
 Compounds = Chemical Change – 2 or
more different atoms bonded
 Mixtures = Physical Change – 2 or more
substances mixed (heterogeneous)
 Solution = Physical Change – 2 or more
substances mixed (homogeneous)

Solution = at least 2 substances mixed;
type of mixture that is homogeneous

The test is on Sessions 1-10, the second
section of your table of contents.
Yes, the study guide is a great review, but
don’t forget about everything else we did…
◦ Can you calculate density?
◦ Do you know the 5 indicators of a chemical
change?
◦ Don’t forget about metallic bonds?
◦ Do you know what all of the vocab terms in the
second column of your vocab list mean?

You can start anywhere…bring your notes!
Find the station name on your answer sheet
Write the question down
Search for the answer; write the answer down
The station where you found the answer
becomes your next question
If you end up at the same station twice you
have made a mistake!
Ms. Sarnelli is the Rescue Station if you think
you may have made a mistake.
