Periodic Table Inquiry
Post Lab Discussion
Post Lab Due Monday for Blue classes and Tuesday for Gold classes. For this summative activity, please turn in your
completed packet with pre-lab and data, as well as an attached conclusion.
In your conclusion… Identify both unknowns using your calculated density
and physical observations.
Identify sources of error that may influence the outcome of your investigation.
Reflect upon this activity and analyze your
performance and effort.
Summative Quiz 3
LUCKY YOU!
Your summative quiz 3 will now be on… Monday September 18th, for Blue classes
Tuesday September 19th, for Gold classes
The Periodic Table
How the periodic table is put together
What is the Periodic Table?
It is an organizational system for elements.
Who created it?
The quest for a systematic arrangement of the elements started with the discovery of individual elements.
By 1860 about 60 elements were known and a method was needed for organization.
In 1869, Russian chemist Dimitri Mendeleev proposed arranging elements by atomic weights and properties.
The table contained gaps but Mendeleev predicted the discovery of new elements.
So how is it arranged?
The genius of the periodic table is that it is organized like a big grid. The elements are placed in specific places
based on the way they look and act. If you have ever looked at a grid, you know
that there are: Rows (left to right) Columns (up and down)
You've got Your Periods...
All of the rows go left to
right.
Each of the rows is
considered to be a
different period
And you got your groups…
When a column goes from top to bottom, it's called a group.
What do all the numbers mean ?
Other than periods and groups, the table is divided into
families.
•Very reactive metals
that do not occur
freely in nature
•Malleable, ductile,
good conductors of
heat and electricity
•Can explode if they
are exposed to water
ALKALI METALS
•Metals
•Very reactive
•Not found free
in nature
ALKLINE EARTH METALS
•Ductile and malleable,
and conduct electricity
and heat
TRANSITION METALS
•Many are man-made
RARE EARTH ELEMENTS
•Are ductile and malleable
•Are solid and have a high density
OTHER METALS
•Have properties of both metals and non-metals
•Semi-conductors
METALLOIDS
•Not able to conduct electricity or heat very well
•Very brittle
NON-METALS
•“Halogen" means "salt-former“
• Compounds containing halogens are called "salts"
•Exist in all three states of matter
HALOGENS
•Do not form compounds easily
NOBLE GASES
