Periodic Table Test of Knowledge
Ms. Johnson’s Sixth Grade Science
Labeling Information on the Periodic Table of Elements
• Symbol
• Atomic Mass
• Atomic Number
• Name
Select the pen tool from the box on the bottom left hand corner of this page and use it to draw a line from each label to its place on the periodic table. When you are done select automatic pointer and click the bottom right arrow to check your answer.
Labeling Information on the Periodic Table of Elements
• Symbol
• Atomic Mass
• Atomic Number
• Name
Check your answers with this guide. How did you do? You will need to know this information for the rest of the test. So go back and review if you need to!
Identifying Parts of the Periodic Table
Use the square below to click on the part of the periodic table that tells the atomic mass of the element.
Identifying Parts of the Periodic Table
Your answer is incorrect. The number eight is the atomic number for oxygen. It represents the number of protons in one atom of the element oxygen. Click the left back button to try again!
Identifying Parts of the Periodic Table
Your answer was incorrect. You selected the atomic symbol. Click the left back button and try again!
Identifying Parts of the Periodic Table
Not quite! The word you selected is the name of the element. Click the left back button and try again.
Identifying Parts of the Periodic Table
You got it! The number 16.00 is the atomic mass of oxygen. If you subtract the atomic number from the atomic mass, you will find the number of neutrons in one atom of oxygen!
Counting Protons in an Element
Look at the insert from
the periodic table to your
left. How many protons
are in one atom of
Potassium?
• 19
• 20
• 39.10
HINT
Counting Protons in an Element
Way to go! The atomic number is the same as the number of protons in one atom of the element. You are correct. Potassium has 19 protons and 20 neutrons!
Counting Protons in an Element
Sorry. Twenty
represents the number of
neutrons in the atom, not
the number of protons.
Check out the hint and
try again!
HINT
Counting Protons in an Element
Sorry. The number you
selected is the atomic
mass for Potassium, not
the atomic number.
Check out the hint and
try again!
HINT
HINT
• The number of protons is equal to the atomic number.
• The atomic number is located above the symbol in any square in the periodic table of elements.
• Good luck!
Finding the Number of Neutrons in an Atom
Look at the insert from
the periodic table to your
right. How many
neutrons are in one
atom of Boron?
• 5
• 7
• 10.81
HINT
Finding the Number of Neutrons in an Atom
Sorry. The number 5 is
the atomic number for
Boron. This means that
Boron has 5 protons, not
neutrons. Check out the
hint and try again!
HINT
Finding the Number of Neutrons in an Atom
You got it! When you
subtract the atomic
number (5) from the
atomic mass (10.81), you get
the number 6.81. When you
round this number to the
nearest whole number you
find that Boron has 7
neutrons! Nice work!
Finding the Number of Neutrons in an Atom
Sorry. The number
10.81 is the atomic mass
of Boron. Check out the
hint and try again!
HINT
HINT
• To find the number of neutrons in an atom you subtract the atomic number from the atomic mass and round to the nearest whole number.
• Atomic Mass – Atomic Number = Neutrons
• Use a sheet of paper to solve this problem
• Good luck!
Using the Periodic Table of Elements
On a sheet of paper write
down the names of the
elements listed to the
right. Use this link to
The Periodic Table of
Elements to find the
symbol for each
element listed on the right.
Name Symbol
Iron _____
Copper _____
Sodium _____
Berylium _____
Tin _____
Using the Periodic Table of Elements
Did you get them all
right. Remember that
the symbol is sometimes
an abbreviation of the
Latin word. Don’t let
this confuse you!
Name Symbol
Iron Fe
Copper Cu
Sodium Na
Berylium Be
Tin Sn
Using the Periodic Table of Elements
On a sheet of paper write
down the atomic numbers for
the elements listed to the
right. Use this link to
The Periodic Table of
Elements to find the
Name of the element that
matches the atomic number
to the right.
Atomic # Name
82 _____
16 _____
1 _____
36 _____
80 _____
Using the Periodic Table of Elements
So……How did you do?
Remember that all of the
elements are listed in
order by atomic number.
Were there any
elements that you knew
without using the
periodic table?
Atomic # Name
82 Lead
16 Sulfur
1 Hydrogen
36 Krypton
80 Mercury
CONGRATULATIONS!
