manganese(III) flourideManganese(III) fluoride
Manganese IV fluoride: The first thing you should realize right off the bat is that this compound is composed of the elements manganese (Mn) and fluorine (F). My guess is that it is the IV throwing you off. :) The IV is usually in parentheses and indicates the positive charge on the preceding element. These designations are used if the preceding element can have more than one charge. It is generally only used with the transition metals (iron is the classic example). Therefore, the manganese (Mn) has a charge of +4. Since we also have fluoride, we can create our compound! Fluoride has a -1 charge. So... Mn4+ and F- The combination to give this compound a charge of zero is: MnF4

MnF3 is Manganese(III) fluoride, otherwise known as Manganese trifluoride.

Fluorine is found in nature always in chemical compounds with elements like sodium, potassium, magnesium, calcium, aluminum, boron, carbon, iron, lithium, nickel, phosphorus, silicon, strontium, and titanium. The only way to separate these compounds and to get pure florine is by electrolysis, which involves using large amounts of electricity and usually quite low temperatures. By the way, you don't want any pure fluorine because it is corrosive, explosive, and deadly.
