Atomic Model
Learning Targets: -Use the atomic model to diagram elements of various elements. Calculate atomic mass and number of electrons, protons, and neutrons in a given element
Over the past few days you have learned about the subatomic particles in atoms and their charges. We have also viewed a few ideas in video form of how to go
about building a model of an atom. In class, I will provide large beads, wire, string, hot glue gun, paint, and other basic supplies to build your atom model. Please
feel free to bring in your own supplies if you would like to use them instead.
In this lab, you will build a 3D model of one of the elements listed below (circle the one that you are choosing):
Element 1 = 3 protons
Element 2 = 2 electrons
Element 3 = 5 protons
Write your chosen element’s name_______________________, mass number ___________, and number of neutrons______________
In the square draw a diagram of your chosen element’s atom
Include correctly labeled protons, electrons, neutrons.
Use a
+ sign to show positive, - sign to show negative, and
no sign to show neutral charges
After you have drawn your diagram, you may begin building your 3D model!
Please turn in this sheet with your model!
Scoring Guide for your Model:
5 Points
Protons, electrons, &
neutrons are in the
correct places in the
atom and labeled
correctly. (correct # of
subatomic particles)
Model is neat and
colorful (at least 3
colors are used)
4 Points
Protons, electrons, &
neutrons are in the
correct places in the
atom but 1 may be
missing a label or
mislabeled(mostly
correct # of subatomic
particles)
Model is mostly neat
and includes at least 3
colors
Totals:
Sum of Totals X 2 = _______/20
3 Points
Protons, electrons, &
neutrons are mostly in
the correct places in
the atom but may be
missing a labels or
mislabeled (somewhat
correct # of subatomic
particles)
Model is acceptable
with enough color to
distinguish between
subatomic particles
2 Points
Protons, electrons, &
neutrons are mostly in
the correct places in
the atom but are
mislabeled or not
labeled. (somewhat
correct # of subatomic
particles)
Model is a bit messy
and there is enough
color to distinguish
between subatomic
particles
1 Points
Protons, electrons, &
neutrons are mostly
NOT in the correct
places in the atom and
are mislabeled or not
labeled. (somewhat
correct # of subatomic
particles)
Model is messy and
there is not enough
color to distinguish
between subatomic
particles
0 Points
Protons, electrons, &
neutrons are NOT in
the correct places in
the atom and are not
labeled. Model is
incomplete or is
missing at least one
subatomic particle
Model is incomplete,
lacks color, and is
messy
