These are questions that relate to the notes you took on [[Periodic Trend Notes for Powerpoint]]. 
 
When you are discussing Periodic Table and its trends, Across a Period means from left to right on the same row (also called Period) of the Periodic Table. 
 
1. As you down a Group does the Coulombic Force (CF) decrease or increase or stay the same or no specific trend. Explain the reason for the trend. 
 
 
 
 
2. As you go across a Period, does the CF decrease or increase or stay the same or no specific trend? Explain the reason for the trend. 
 
 
 
 
 
3a. If the Periodic Table is a rectangle, what corner would include element whose nucleus have the greatest pull (highest CF) to the valence electrons? Top left, Top right, Bottom left, Bottom right?
 
 
3b. What corner would include elements whose nucleus have the WEAKEST pull (LOWEST CF) to valence electrons? 
 
 
4. As you go down a Group, does Atomic size (also called Atomic radii) decrease or increase or stay the same or no specific trend? 
 
 
5. As you go across Period, does Atomic size decrease or increase or stay the same or no specific trend? Explain 
 
 
 
 
6. For the following elements, align from smallest to largest Atomic size, Cr, P, Ca, Cs, Ne. 
 
7a. What is the definition of Ionization Energy (IE)? 
 
 
7b. How does Ionization Energy and the CF of the nucleus to the valence electron relate? 
 
 
8. As you go down a Group, does the IE decrease or increase or stay the same or no specific trend? Explain. 
 
 
9. Does IE decrease or increase or stay the same or no specific trend as you go across the Period? 
 
10. If you look at just the 2nd row of the Periodic Table, which element would you expect to have the highest IE? 
 
11. What are the elements that are involved in the 1st Exception of the IE trend and why is it an exception? 
 
 
12. What is the 2nd Exception to IE as you go across Period. Explain why. 
 
 
 
13. Align the following elements by decreasing IE: K, F, C, Al 
 
14. If the Periodic Table is a rectangle, what corner would include element whose IE is the lowest? Top left, Top right, Bottom left, Bottom right?
