molecule

Introduction

molecule (mŏlˈəkyōl) [key] [New Lat., = little mass], smallest particle of a compound that has all the chemical properties of that compound. A single atom is usually not referred to as a molecule, and ionic compounds such as common salt are not made up of molecules. Unlike ions, molecules carry no electrical charge.
