Objectives:

1. Students will determine the Periodic Trends for several properties.

2. Students will explore the Force of Attraction.

3. Students will use the Force of Attraction to justify all the Periodic Trends.

Warm-Up: 

1. What is Force of Attraction (F_A)?

2. What are the period and group trends for Force of Attraction (F_A) and why are the trends this way?

(hint: Use Coulomb's Law) 

Apply the period and group trends to answer the following:

3. List the following elements in order from largest to smallest atomic radius: I      Ba      S      P

4. List the following elements in order from largest to smallest electronegativity: Ne      F      Cl      S
