Both were thought to differ in gender. The malemagnes had a property to attract iron, and was the iron ore we nowknow as lodestone or magnetite, and which probably gave us theterm magnet. The female magnes ore did not attract iron, but wasused to decolorize glass. This feminine magnes was later calledmagnesia, known now in modern times as pyrolusite ormanganese dioxide. The metal isolated from it became known asmanganese later on.Chemical & Physical PropertiesName: ManganeseSymbol: MnAtomic Number: 25Atomic Mass: 54.938049 amuBoiling Point: 1962.0 °C (2235 K, 3564 °F)Melting Point: 1246 °C (1519 K, 2275 °F)Number of Neutrons: 30Number of Protons/Electrons: 253Atomic Volume:7.39 cm /molClassification: Transition MetalOther FeaturesWhat is Mn Ore ?Crystal Structure: cubic: body centered3Density @ 293 K: 7.43 g/cmColor: silverish/grayish“Mn” is the chemical symbol of manganese. It is a brittle, sivery- graymetal that looks much like iron. It is difficult to fuse, but easy tooxidize. Manganese in alloy form is an essential input in steel making,Manganese is the 12th most abundant element widely distributed inthe earth's crust and the fourth most used metal after iron,aluminium and copper._____________________________________________________________________________________A C Choksi Institutional Researchresearch@acchoksi.com 17
