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
