Question

Quizplus · Accepted Answer

Molecular forces and everyday forces are best understood in terms of electromagnetic interaction. The electromagnetic force is responsible for the interaction between charged particles, including the electrons that make up the outer shells of atoms. These interactions give rise to the various types of bondings (ionic, covalent and metallic) that hold molecules together. Moreover, other everyday forces we observe, such as friction, tension, and compression, also can be explained by electromagnetic interactions at  microscale.
