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.
Conqueror and king of Macedonia, Alexander the Great was born on July 20, 356 B.C., in Pella, Macedonia. During his leadership, from 336 to 323 B.C., he united the Greek city-states and led the Corinthian League. He also became the king of Persia, Babylon and Asia, and created Macedonian colonies in the region.hile considering the conquests of Carthage and Rome, Alexander the Great died of malaria in Babylon (now Iraq), on June 13, 323 B.C. He was just 32 years old. Rhoxana gave birth to his son a few months later.
