Today we are going to focus on the
Periodic Table!
• Activating Strategy…
– BRAINPOP!
A Beautiful Mind
This crazy looking
man is Russian
chemist DMITRI
MENDELEEV.
Mendeleev created
the first Periodic Table
in 1869.
So why is the PToE important?
•ORGANIZATION.
– There are a lot of elements on earth. If we
don’t know anything about them/what they
have in common, we can’t understand them.
THINK, PAIR, SHARE: (2 minutes) Think back to the end
of Earth’s History. We learned about another system
of organization that scientists use. What was that
system and what did it do?  HINT: Think evolution!
So how is the Periodic Table
organized?
• Vertical Columns = groups
• Horizontal Rows = periods
Your periodic table already has the groups (those gray boxes I
told you not to color), let’s label the periods.
Each element lives with its own
Family
• Elements on the periodic table can be
grouped into families based on their
chemical properties.
• Each family has a specific name to
differentiate it from the other families in the
periodic table.
• Elements in each family
react differently with
other elements.

DO NOW!
1. Find the element and identify its family:
-
Group 6, Period 5
Group 5, Period 4
Group 17, Period 2
Noble gas with atomic symbol “Ne”
Transition metal with atomic symbol “Ag”
PLEASE DO NOT TOUCH ANYTHING ON YOUR LAB
TABLES!
Let’s mix it up…
• 4 stations – 20 minutes at each station.
• Each station has notes, directions, an activity,
and clean up instructions.
• Please be responsible with the materials.
• Expectations:
– Work together
– Low volume
– Complete the activity
– Stay in your assigned group
Gallery Walkers
• Because Ms. K will be working with 1 group of
students while you are doing your gallery walk, it is
IMPERATIVE that you follow these rules & directions.
• You will have exactly 1 song per station.
• Do NOT move until the music changes.
• Do NOT move before the music changes.
YOU MUST BE ON TASK, QUIET, AND AT YOUR ASSIGNED
STATIONS AT ALL TIMES OR MS. K WILL ASK YOU TO
SIT DOWN.
-Organize on your plate a HELIUM (He) atom!
-Draw what your plate looks
like
2
H
Helium
4.00260
• Now change your Helium atom into an ION
with a charge of -1 on your plate!
• Draw it!
2
H
Helium
4.00260
• Draw a Beryllium (Be) atom!
4
Be
Beryllium
9.01218
• Make your Beryllium atom into an Ion with a
charge of +2
4
Be
Beryllium
9.01218
• Draw a Lithium atom.
3
Li
Lithium
6.941
• Make the Lithium atom into an Ion with a
charge of -3.

Li
Lithium
6.941
ALKALI METALS
Group 1
• Hydrogen is not a member, it
is a non-metal
• 1 electron in the outer shell
• Soft and silvery metals
• Very reactive, esp. with water
• Conduct electricity

ALKALINE EARTH METALS
Group 2
• 2 electrons in the
outer shell
• White colored and
malleable
• Reactive, but less
than Alkali metals
• Conduct
electricity
TRANSITION METALS
Groups in the middle
• Good conductors of
heat and electricity.
• Some are used for
jewelry.
• The transition metals
are able to put up to
32 electrons in their
second to last shell.
• Can bond with many
elements in a variety
of shapes.
Halogens
Group 17
• 7 electrons in the
outer shell
• All are nonmetals
• Very reactive are
often bonded with
elements from
Group 1
Noble Gases
Group 18
 Exist as gases
 Non-metals
 8 electrons in the
outer shell = Full
 Helium (He) has
only 2 electrons in
the outer shell = Full
 Not reactive with
other elements
Let’s Practice!
• You and your partner are responsible for:
– Using your new colored periodic table as a
reference.
– Answering ALL investigation questions.
– Raising your hands when you have questions.
– COLLABORATING SUCCESSFULLY to complete
work during the given time 
– Value- 50 point in class assignment.
Use your knowledge & periodic table to help you identify the
following elements. Also include what FAMILY they belong to
(complete in your notebook):

• HOT Q1: Why is it important to have a system
of organization for all of the elements on
earth?
• HOT Q2: Why do only electrically stable
elements live on the Periodic Table?
• HOT Q3: What are the 2 most reactive groups?
Why are they so reactive?
HOT Q4: Why don’t the noble gases react?
