AP Bio Unit 1 - Electronegativity

Which element has the highest electronegativity?

• Sodium (Na)

• Fluorine (F)

• Nitrogen (N)

Which element will tend to lose electrons due to its very low electronegativity?

• Hydrogen (H)

• Sodium (Na)

• Fluorine (F)

If there is little to no difference in electronegativity between two atoms, the bond between them will most likely be:

• Polar

• Non-polar

In which type of bonds will you find partial charges on the molecule?

• Non-polar covalent

• Polar covalent

Refer to the image below.  If a bond forms between Nitrogen (N) and Hydrogen (H), will it be polar or non-polar?

• polar

• non-polar
