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.

Iodine is a slate-grey crystalline that was discovered by Bernard Courtois in 1811. It is very important to the human body to maintain a chemical process called metabolism. Iodine comes from the Greek word lodes meaning violet.
Iodine is found in seawater but is too diluted to recover economically; however sea plants such as kelp absorbs the element from the seawater making it rich in iodine. The kelp is shredded and mixed with water then filtered so you’re left with rich iodide ions. Britain, France and Japan are the world’s leading producers of iodine using this method.
Iodine is used for a variety of things. In photography...
