Electronegativity Worksheet
Name___________________________________
Block _________
1. How are ionic bonds and covalent bonds different?
2. How does a polar covalent bond differ from a non-polar covalent bond?
3. How do electronegativity values help us determine the polarity of a bond?
4. Fill in the values to complete the following table for predicting bond type based on differences in
electronegativity.

5. Does electronegativity increase or decrease when you go across a period on the periodic table?
Does it increase or decrease when you move down a group on the periodic table?
6. For each of the following sets of elements, identify the element expected to be most
electronegative (circle) and which is expected to be least electronegative (cross out), based on
their position in the periodic table.
a. K, Sc, Ca
b. Br, F, At
