Step #3 - Sulfide (the anion) means S 2 ¯. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound. Potassium was discovered and first isolated by Sir Humphrey Davy in 1807.
