Manganese and Iodine are both elements on the periodic table. Both are used greatly in our lives every day. Manganese is a brittle metallic element that is important in many industrial processes. It was discovered by Carl Wilhelm Scheele in 1774. Manganese was given its name from the Latin word magnes meaning magnet. Manganese belongs to a set of elements called the transition metals. Manganese is the 12th most common element found in the earth’s crust and is the 4th most common medal mined. It is also found in meteorites, asteroids and some comets. Manganese is widespread in lava rock but it is not present in very high amounts so, it’s not worth digging up the rock to extract it. Instead mining companies mine the manganese from deposits that form from chemical changes in the rocks after millions of years. Manganese also grows under water; it builds up on a tiny piece of rock or even a shark tooth and increases by a fraction of an inch every million years. Manganese is used for many things from steel to spacecraft to batteries. It is also used for purifying water and forms very brightly coloured compounds used for glazing pottery and glass.
