The difference in electronegativity between two bonded atoms determines the bond's polarity, with a large difference indicating a polar covalent bond (e.g., H-F bond) and a small difference indicating ...

is locked away at the centre and no matter what direction you approach the molecule from you see a \(\delta-\) charge. This means that the molecule itself is non-polar due to symmetry.

When a charged object such as a rubber balloon is brought close to a fine stream of a polar liquid, the stream is attracted toward the electrical charge. If the same charged object is brought close to ...
