Directions:

• Use this lesson to complete the notes sheet titled NOTES: Patterns in the Periodic Table.

• When you are finished, glue the notes sheet into your composition notebook.
  

Family Name: Alkali Metals

Group/Column Number: 1

Number of Valence Electrons: 1

Elements in the Group: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr)

Alkali Metals

• very reactive

• readily bond with other elements and lose the one valence electron

• react violently when come in contact with water  

Chemical Properties

• shiny, soft metals 

• sometimes soft enough to be cut with a dull knife 

• malleable 

• ductile 

• good conductors of electricity and heat 

Physical Properties

Family Name: Alkaline Earth Metals

Group/Column Number: 2

Number of Valence Electrons: 2

Elements in the Group: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra)

Alkaline Earth Metals

• fairly reactive, but not as reactive as the alkali metals

• react with halogens to form compounds

• burn with colored flames  

Chemical Properties

• silvery, shiny, and relatively soft metals

• malleable 

• ductile 

• good conductors of electricity and heat 

Physical Properties

Family Name: Transition Metals

Group/Column Number: 3 through 12

Number of Valence Electrons: 2 or 3

Elements in the Group: titanium (Ti), copper (Cu), nickel (Ni), silver (Ag), platinum, gold (Au) and many more

Transition Metals

• form compounds with different colors 

Chemical Properties

• shiny

• malleable 

• ductile 

• good conductors of electricity and heat 

Physical Properties

Family Name: Halogens

Group/Column Number: 17

Number of Valence Electrons: 7

Elements in the Group: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)

Halogens

• form acids when combined with hydrogen

• fairly toxic

• readily combine with metals to form salts

• highly reactive

Chemical Properties

• nasty smell 

• poor conductors of electricity and heat 

Physical Properties

Family Name: Noble Gases

Group/Column Number: 18

Number of Valence Electrons: Helium has 2 and the rest have 8

Elements in the Group: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn)

Noble Gases

• non-reactive (inert)

• non-flammable

• stable

Chemical Properties

• colorless, odorless gases

• low melting and boiling points

Physical Properties
