General Introduction on Selenium,Selenium was discovered by Jöns Jacob Berzelius, a Swedish chemist, in the year 1817. He believed the element that was contaminating the sulphuric acid being produced at a factory in Sweden was tellurium. He realised he had found a new element. Berzelius suggested naming the element selenium; from the Greek word . for “moon”.
