Manganese's atomic number is 25 and its symbol is Mn. Manganese is a transitional metal that is often combined with other metals to create stainless steel. It is hard but brittle. Manganese compounds can readily be found in the topmost layers of the earth’s crust. Manganese is capable of forming oxides with vibrant magenta hues as well as a variety of greys. This capability was utilized by many ancient civilizations in glassware and paintings. Manganese has been found in cave paintings that are over 24,000 years old.

About 80% of the known world manganese resources are in South Africa with a total estimate of 15 billion tons. This amount pales in comparison to the estimated 500 billion tons of manganese nodules on the ocean floor. However, because it is not feasible to collect it from the ocean floor, South Africa remains the leading source of global manganese.

Safety

We get asked about the radioactivity and overall safety of the periodic tables/cubes from time to time. These are legitimate concerns and we wanted to address those concerns here. Although there are several elements in the cubes that are dangerous or toxic, the acrylic and glass ampules make the products safe to handle and store.

The average American is exposed to 0.034 mrem/hr from background radiation (300 mrem/year). In other words, a person will get three times the radiation from natural background radiation which includes the sun, food, radon, and the environment, than they will from holding a radioactive element in one of our Lucite Acrylic displays.
