Use the periodic table to determine the characteristics of an element
Explain the matter has properties that are determined by the structures and the arrangement of its atoms

Explain how elements are arranged on the periodic table
Describe the difference between a period and group
Explain why elements in a group often have similar properties
Describe the properties of the elements in groups of the periodic table
Period GroupPeriodicValence electron (12.1)Alkali metalAlkaline-earth metalHalogen Noble gas
Elements on the periodic table can be grouped into families bases 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.

What do you remember about these from the previous unit? Metals: where are they found on the periodic table?
▪ Properties— ▪ Ductile▪ Conduct Electricity and heat▪ Solid at room temperature▪ Malleable and Shiny!
Non-Metals: where are they found on the periodic table?▪ Properties—
▪ Not malleable or ductile▪ Breakable▪ Not shiny as a solid▪ Poor conductor
Metalloids: where are they found on the periodic table?▪ Properties—
▪ Mixture of the two; Brittle but shiny; semi-conductor of heat and electricity
Group 1 Hydrogen is not a
member, it is a non-metal
1 electron in the outer shell
Soft and silvery metalsVery reactive, esp. with
water Conduct electricity

Group 2 2 electrons in
the outer shell White and
malleable Reactive, but
less than Alkali metals
Conduct electricity
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.
Group 3 3 electrons in
the outer shell
Most are metals
Boron is a metalloid
Group 4 4 electrons in
the outer shell Contains
metals, metalloids, and a non-metal Carbon (C)
Group 5 5 electrons in
the outer shell Can share
electrons to form compounds
Contains metals, metalloids, and non-metals
Group 6 6 electrons in
the outer shell Contains
metals, metalloids, and non-metals
Reactive
Group 7 7 electrons in
the outer shell All are non-
metals Very reactive
are often bonded with elements from Group 1
Group 8Exist as gasesNon-metals8 electrons in
the outer shell = Full
Helium (He) has only 2 electrons in the outer shell = Full
Not reactive with other elements
Some are Radioactive
The rare earths are silver, silvery-white, or gray metals.
Conduct electricity
