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
