This is what causes atoms to bond and what holds a molecule together. Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules attract and hold one ...

Researchers have developed a novel molecular thermometer that can determine temperature fluctuations within cells.

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

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 ...
