Groups of the Periodic Table

Names of the columns

• Elements in groups behave similarly.

• Many of the important groups have names.

Group 1

Alkali Metals

Multiple Choice

Which of these elements is an Alkali Metal?

• Cs

• Fe

• C

• Kr

Alkali Metals

All have 1 valence electron

All VERY reactive!

• So reactive they are never found in pure form in nature.

• Always in compounds.

• The get more reactive as you go down the column.

Group 2

Alkaline-Earth Metals

Multiple Choice

Which of these is an Alkaline Earth Metal?

• Mg

• Na

• Sc

• U

Alkaline-earth Metals

All have 2 valence electrons

Alkaline-earth Metals

• Also reactive

• Never found in pure form in nature.

• Not as reactive as the Alkali Metals though.

Group 17

Halogens

Multiple Choice

Which of these is a halogen?

• I

• S

• Ar

• Po

Halogens

All have 7 valence electrons

Halogens

Also VERY reactive!

Group 18

Noble Gases

Multiple Choice

Which of these is a Noble Gas?

• He

• F

• O

• S

Noble Gases

All have 8 valence electrons

(except for He, it has 2!)

Noble Gases

• Very UNreactive!

• Virtual never found in compounds.

Groups 3-12
