 Answer the following question in a clear, concise manner. 
 
 
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. If the Periodic Table is a rectangle, what corner would include the element whose nucleus have the greatest pull (highest CF) to the valence electrons? Top left, Top right, Bottom left, Bottom right? 
 
_____________________________ 
 
3. As you go across a Period (row), does Atomic size (AR) decrease or increase or stay the same or no specific trend? Explain 
 
 
 
 
4. If the Periodic Table is a rectangle, what corner would include the element with the SMALLEST atomic radii/size (AR)? Top left, Top right, Bottom left, Bottom right?

5. Electronegativity (EN) has a long complicated definition. What did I say it actually means. 
 
 
 
6. As you go across a Period, does the EN decrease or increase or stay the same or no specific trend? Explain the reason for the trend. 
 
 
 
 
 
7. If the Periodic Table is a rectangle, what corner would include the element with the LARGEST (or greatest pull to its valence electrons)? Top left, Top right, Bottom left, Bottom right?
