Detailed Explanation: Why is HI a Polar Molecule? Definition of Covalent bond: When two or more atoms exchange their electrons to stabilize each other in the bond of the molecule, these bonds are formed with mutual sharing of electrons. Im a mother of two crazy kids and a science lover with a passion for sharing the wonders of our universe. The student used to ask Is NH3 polar or nonpolar? here in this post to investigate the possibilities. Dipole moments, for example, do not exist in molecules that can be mirrored/flipped around a molecular geometric plane because dipole moments are only a single point. To decide whether a NH3 molecule is nonpolar or polar, the electronegativity value of all N-H bonds of NH3 molecule must be considered.
