Electronegativity and molecular polarity are central to understanding chemical bonding. By combining periodic trends with molecular geometry, you can predict whether a molecule is polar or nonpolar.

Bond polarity is all about how atoms share electrons—and when that sharing isn’t equal, fascinating things happen. From electronegativity differences to molecular geometry, these factors decide ...

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 ...
