In a polar molecule, electron distribution around the entire molecule is

• symmetrical

• asymmetrical

What makes a molecule nonpolar? (check all that apply)

• No lone pairs on the central atom

• uneven electron distribution

• all terminal (outside) atoms are the same

• a large electronegativity difference between the two elements in the molecule

Classify the polarity of this molecule

• polar covalent

• nonpolar covalent

• ionic

In a polar covalent bond, the electrons spend more time and localize around the atom...

• with the Greatest Electronegativity

• with the Lowest Electronegativity

• Each atom Equally

In a nonpolar covalent bond, the electrons spend more time and localize around the atom...

• with the Greatest Electronegativity

• with the Lowest Electronegativity

• Each atom Equally
