Historically, dem name manganese based on pyrolusite and other black minerals from the Magnesia region for Greece, wey also give name to magnesium and iron ore magnetite. By the mid-18th century, Swedish chemist Carl Wilhelm Scheele don use pyrolusite produce chlorine. Scheele and others know say pyrolusite (wey we now sabi say na manganese dioxide) get new element inside am, but dem no fit isolate am. Johan Gottlieb Gahn na the first person wey isolate impure sample of manganese metal for 1774, wey he do by reducing the dioxide with carbon.

Manganese phosphating dey use for rust and corrosion prevention for steel. Ionized manganese dey use industrially as pigments of different colors, wey depend on the oxidation state of the ions. The permanganates of alkali and alkaline earth metals dey powerful oxidizers. Manganese dioxide dey use as the cathode (electron acceptor) material for zinc-carbon and alkaline batteries.

For biology, manganese(II) ions dey function as cofactors for plenty enzymes wey get different functions. Manganese enzymes dey very essential for detoxification of superoxide free radicals for organisms wey need to deal with oxygen. Manganese also dey function for the oxygen-evolving complex of photosynthetic plants. While the element na required trace mineral for all living organisms wey we sabi, e fit also act as neurotoxin if e plenty. Especially through inhalation, e fit cause manganism, wey be condition for mammals wey fit lead to irreversible neurological damage.

Based on the article and the following list of answers, write a list of questions.

1. Manganese element
2. rust and corrosion prevention on steel
3. stainless steels.
