1. Define electronegativity
2. Describe what factors impact the electronegativity of an atom
3. Explain why fluorine has a higher electronegativity than magnesium.
4. Explain why fluorine has a higher electronegativity than bromine
5. Describe how a polar bond arises
6. Explain how differences in electronegativity result in a continuum of bonding
between non-polar bonds and ionic bonds
7. Explain how an ionic bond arises regarding electronegativity
8. Draw the polarities on a C-Cl bond
9. Draw the polarities on a O-H bond
10. Explain why ionic substances dissolve in water and not hexane (you will need to
research this)
11. Between which two atoms would result in the most polar bond
12. For the following molecules
a. Draw the shape (include dipoles on bonds in relevant)
b. Name the shape
c. State if the overall molecule is polar or non-polar and explain why (you will
need to read the revision guide to help you here)
i. SiF4
ii. PCl3
iii. BeCl2
iv. NH3
v. CO2
vi. H2O
