Electropositive ions
When an atom looses one or more electrons to get stability, The number of electrons lost by an atom of an element is its Positive valency and the ion is called Cation or Electropositive ion. (or) Radical or ion having positive charge on them is called Electropositive ion (or) Cation.
Properties of Electropositive ions
1. They are called Basic Radicals.
2. Metals which have 1 to 3 electrons in outermost orbit (Valence shell) looses electrons and converts to Electropositive ions
3. The number of electrons in electropositive ions are less in number than protons due to loss of electons
4. The Size of the Electropositive ion is considerably less than a neutral atom due to increase of attractions of Protons on electrons left after froming ion.
5. Size of the Electropositive ion is inversly proportional to number of electrons lost for a particular element.
