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. Electronegativity (EN) has a long complicated definition. What did I say it actually means.
2. As you down a Group does the EN decrease or increase or stay the same or no specific trend. Explain the reason for the trend.
3. 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.
4a. If the Periodic Table is a rectangle, what corner would include element with the highest EN? Top left, Top right, Bottom left, Bottom right?
4b. What corner would include elements with lowest EN?
5. Align the following elements by INCREASING EN ; Si, Rb, Cl, Cr
6. As you go down a Group, does Ionic radii/size (IR) decrease, increase, stay the same or no specific trend?
7.. Where are metals located on Periodic Table? Non-metal? What on the Periodic Table indicates location of each?
8. What do Metals do with their valence electron and why?
9. What do Non-metals do with their valence electrons and why?
10. For metals, is atomic radii (AR) greater than, less than, or same as Ionic radii (IR)?
11. For non-metals, is AR greater than, less than, or same as IR? Explain why.
12. As you down a Group does the Metallic Characteristic (MC) decrease or increase or stay the same or no specific trend?
13. As you go across a Period, does the MC decrease or increase or stay the same or no specific trend? Explain the reason for the trend.
14. If the Periodic Table is a rectangle, what corner would include element with the highest MC? Top left, Top right, Bottom left, Bottom right?
15. What question above did you justify when you correctly answered Q14?
16. Align the following elements from lowest to highest MC ; Ba , S, Cl, Ag, As
