Chemical polarity, also known as bond polarity or simply polarity, is a concept in chemistry which describes how http://www.answers.com/topic/chemical-bond http://www.answers.com/topic/electron are shared between http://www.answers.com/topic/atom. It is a physical property of compounds and affects other physical properties such as http://www.answers.com/topic/solubility, http://www.answers.com/topic/melting-point and http://www.answers.com/topic/boiling-point. Polarity also affects http://www.answers.com/topic/intermolecular-force, leading to some compounds or molecules within compounds being labelled as polar or non-polar.
