Module 6 & 7

Families of the Periodic Table Main Groups

• 1A - Alkali Metals

• 2A - Alkaline Earth Metals

• 7A - Halogens

• 8A - Noble Gases

Trends in the Periodic Table

• Electronegativity

• Ionization Energy

• Atomic Radius

• 
  

Electronegativty

• Most electronegative are the Halogens

• Tend to keep the electrons closer to them

• Increases from Left to Right

• Increases from Bottom to Top

Ionization Energy

• Elements with the highest IE are the Halogens

• The higher the IE, the stronger the intermolecular forces

• Increases from Left to Right

• Increases from Bottom to Top

Atomic Radius

• Bigger spread of electrons

• Increases Left to Right

• Increases Top to Bottom

•
