DO NOW WEDNESDAY
• Open up to the Periodic Table you were given
yesterday and color it like the one shown below.
•Today’s PLAN
•To identify properties of groups/families within the periodic table.
•To predict an element’s properties based on its location on the
periodic table.
•Todays DO
•We will complete a graphic organizer about the groups of elements
on the Periodic Table and their properties.
•We will practice identifying elements and their properties using the
Periodic Table.
The Periodic Table
Why is the Periodic Table important
to me?
• You get to use it on your
Unit test.
• It organizes lots of
information about all the
known elements.
• It allows us to make
predictions about
elements we may know
nothing about.
Here is a “periodic” table we are all
familiar with.. What is it?
Certain information is missing.
Can you predict the missing data? How?
?

Organization of the Periodic Table
• One way the Periodic Table is organized allows us to
classify an element as a metal, nonmetal, or metalloid
and make predictions about the physical properties of
elements based upon this classification.
Metals
• Location: on the LEFT side of the Staircase line
and the bottom two rows
• Physical Properties: good conductors, shiny,
malleable, ductile, high density, high melting
point
• Examples include: Sodium, Potassium,
Aluminum, Gold, and Silver
• Uses: wires, cans, nutrients in our bodeis
Metalloids
• Location: Elements that border the Staircase
line on either side (except Aluminum)
• Physical Properties: semi-conductors, some
are shiny, not malleable, not ductile
• Examples include Boron, Silicon, Arsenic,
Antimony, and Tellurium
• Uses: computer chips, poison, treated wood
Nonmetals
• Location: on the RIGHT side of the Staircase
line
• Physical Properties: Poor conductors, gases
or brittle solids with low melting points
• Examples: Carbon, Nitrogen, Oxygen,
Phosphorus, Chlorine, Iodine, Fluorine
• Uses: nutrients in your body, kill germs in pool
water and cuts in your skin, toothpaste to kill
germs
Organization of the Periodic Table
• The Periodic Table is also organized into 18
different columns called groups or families.
• One of these groups is very unique because it
contains only gases that do not react at all under
normal conditions.
• These are the ONLY elements on Earth that will
not react with other elements.
• They are called the Noble Gases.
The Noble Gases
• Location: Elements in
group 18 (last column on
Periodic Table)
• Physical Properties:
VERY unreactive, gases
at room temperature,
poor conductors
• Examples include
Helium, Neon, and Argon
• Uses: lighted “neon”
signs, blimps, and V-day
balloons

properties of Zinc (Zn)?
A. Gas that is unreactive
B. Solid that has a low melting point
C. Solid that is shiny and malleable ✔
D. Gas that is a poor conductor
Periodic Table Practice
4. Which of the following would be physical
properties of Radon (Rn)?
A. Solid that has a high melting point
B. Solid that is malleable and ductile

D. Gas that is very unreactive ✔
Periodic Table Practice
8. Give at least 4 physical properties of Gallium
(Ga). Explain how you knew.
Gallium is a solid that is shiny, malleable,
ductile, and a good conductor. I know
this because Gallium is a metal and these
are physical properties of metals.
