NGSS.HS-PS1-3

• polar

• nonpolar

To which term of reference does the following description refer to?

"an unequal distribution of an electrical charge"

• Polar

• Nonpolar

• Both

Answer explanation

The unequal distribution "or sharing" of electrons results in - one side of a Polar Covalent Bond being partially negative while the other side is partially positive.
