A cation is an ion with positive charge. An ion is an elementary particle or system of elementary particles with a net electric charge. ... Electric charge is a fundamental property of some subatomic particles, which determines their electromagnetic interactions. ...

When naming compounds, the cation is always named first and the anion second. A monatomic cation always takes its name from the name of the element. For example, Ca²⁺ is called calcium. A compound is an area of land that is surrounded by fences, walls, or barbed wire and is used for a particular purpose, especially an area containing buildings and where the entry and exit of people is controlled. ...
