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.
In classical antiquity, Illyria (Ancient Greek: á¼°Î»Î»ÏÏÎ¯Î± or á¼°Î»Î»ÏÏÎ¯Ï, Latin: Illyria, see also Illyricum) was a region in the western part of the Balkan Peninsula inhabited by the Illyrians. The prehistory of Illyria and the Illyrians is known from archaeological evidence.he name Illyria only disappears from the historical record after the Ottoman invasion of the Balkans in the 15th century, and re-emerges in the 17th century, acquiring a new significance in the OttomanâHabsburg Wars, as Leopold I designated as the Illyrian nation the South Slavs on Hungarian territory.
