It's Elemental

Proposed to be an element by Carl Wilhelm Scheele in 1774, manganese was discovered by Johan Gottlieb Gahn, a Swedish chemist, by heating the mineral pyrolusite (MnO 2) in the presence of charcoal later that year.Today, most manganese is still obtained from pyrolusite, although it is usually burned in a furnace with powdered aluminum or is treated with sulfuric acid (H 2 SO 4) to form ...

Manganese | Encyclopedia.com

The element's name is derived from the Latin word magnes, meaning "magnet." This refers to the magnetic property of the common ore pyrolusite. Manganese is the twelfth most abundant transition element (1,060 parts per million of Earth's crust) with twenty-three known isotopes. Large nodules of manganese ore have been discovered on the ocean floor.

Technetium

Technetium is a chemical element with the symbol Tc and atomic number 43. It is the lightest element whose isotopes are all radioactive, none of which is stable other than the fully-ionized state of 97 Tc. Nearly all available technetium is produced as a synthetic element, and only about 18,000 tons are estimated to exist at any given time in the Earth's crust.
