History and Uses
Maganese was discovered by Johan Gahn in 1774 at Sweden. Latin word magnes meaning magnet, or magnesia nigri meaning black magnesia.
Manganese compounds are essential to life. They are essential for the action of some enzymes. Soil deficiencies lead to infertility in mammals and to bone malformation in growing chicks.
Biology (in humans) and Geology (in universe)
Biology: The human abundance by weight is 200ppb. The human abundance by atoms is 23 atoms relative to C=1000000 They are essential for the action of some enzymes.
Geology: Manganese nodules on ocean floors holds contain about 24% manganese. Most Manganese is used from ores in Australia, Brazil, Gabon, India, Russia, and South Africa.
The boiling point is 2061.c and melting point 1246.c density is 7470 kg m‑ , The atom has 25 electrons and the shell structure is 220.127.116.11
Manganese is widely spread throughout the United Kingdom. It is important component of steel. It is Found at the bottom of some oceans. It is used to help dry paint faster. Manganese dioxide was made in paint many years ago. All adult human life will have a total of around 12 mg of manganese in their body.
Manganese metal is gray-white, resembling iron, but is harder and brittle. The metal is reactive chemically, and decomposes cold water very slowly.
