=Iodine= By: Isabella


 * Atomic Number:** 53


 * Protons:** There are 53 protons in iodine.

**Electrons:** There are also 53 electrons in iodine.


 * Neutrons:** 74


 * Average Atomic Mass:** 126.90447


 * Discovery:** T he element Iodine was discovered by Bernard Courtois. At the time of the Napoleonic Wars, Courtois found Iodine. He got saltpeter, but the saltpeter required sodium carbonate which could be isolated by seaweed found on the coasts of Normandy and Brittany. The seaweed was burned and the ash was washed with water. The remaining waste was destroyed by adding sulfric acid. Afterwards, purple vapor rose. Courtois thought he discovered a new element, but did not know for sure.


 * Name:** One of Courtois's friends suggested the name //Iode// from the Greek word //iodes// ( meaning violet) because of the vapor. But the name was decided-//Iodine.//


 * Uses:** Iodine is used to cure foot fungus in horses. Iodine is also found in many disinfectant and water treatments. But it is good to know that the alcohol causes the stinging, NOT the Iodine.


 * Interesting Facts**: Iodine's melting point is 386.85 K, 113.70 C, 236.66 F, and its heat of vaporization is (I2) 41.57 kJ.mol1
