IONIC RADIUS. Ions are formed when the neutral atoms lose or gain electrons. A positive ion or cation is formed by the loss of one or more electrons by the neutral atom whereas a negative ion or anion is formed by the gain of one or more electrons by the atom.The term ionic radii refers to the size of the ions in the ionic crystals.The ionic radius of an ion may vary from crystal to crystal because of change in surrounding ions. The equilibrium distance between the nuclei of the two adjacent ions can be determined by X-ray analysis of ionic crystals.he term ionic radii refers to the size of the ions in the ionic crystals.

Sir William Woodthorpe Tarn, of the British Academy, regarded worldwide as having written the definitive work on Alexander the Great, states in the opening paragraph of his book Alexander the Great that Alexander certainly had from his father (Philip II) and probably from his mother (Olymbia) Illyrian, i.e.
Alexander The Great. Whether Alexander the Great was Greek or just loved things Greek is not important. What is important is that he spread Greek ideas throughout the world in what is known as the Hellenistic Period and was perhaps the most important single person in western civilization with the possible exception of Jesus Christ.
