If there are only two atoms in a molecule, what would make it nonpolar?

In general, if the electronegativity difference between two atoms is less than 0.5, the bond is considered nonpolar, even though the only truly nonpolar molecules are those formed with identical atoms. Nonpolar molecules also form when atoms sharing a polar bond arrange such that the electric charges cancel each other out.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
