Manta's Manganese Mayhem


By Allison P. (Period 2)

   Hi! I'm Manta! I just started junior high! Ever since I found out what a shaman is, I started working on this report about Manganese.
   Manganese is the twenty fifth element on the periodic, making it's atomic number also twenty five. Its atomic mass is 54.94. Its atomic symbol is "Mn".
   In the periodic table, there are many groups, or classifications. Manganese belongs in the transition metals group, which is near the center of the periodic table. It was discovered by Ignatius Kaim in 1770, investigated by Bergman and Scheele, and finally isolated by Johann Gottlieb Gahn. The origin of the name is from the Latin name magnes meaning "magnet".
   Resembling iron, Manganese is a grey-white color. It's harder than iron, yet more brittle. It is very reactive and is used to form important alloys. It is used a depolarizer in dry cells. It makes glass less green when it has been discolored by iron. By itself, it gives glass a reddish color, and is responsible for the true color of amethyst. It is also thought to be an essential for utilization of Vitamin B1. It is found on the bottom of the ocean, and mainly in ores in Russia, Brazil, the Republic of South Africa, Gabon, and India.
   
   This is the model of Magnesium. It has 25 protons and 30 neutrons. The electrons are displayed on the energy level. Magnesium has two valence electrons.    The information was provided by "peral1.lanl.gov", "enviromentalchemistry.com", and the High Point planner.
