Sulfur: The Element of Mystery and Surprise

Sulfur is the tenth most common element in the universe and the 16th most abundant element on Earth. It is a nonmetallic element that appears as a pale, yellow crystalline solid in its natural form. Sulfur has many uses that span from ancient to modern times, and its discovery is an interesting tale that is full of surprises. It is something that we come into contact with on a daily basis, often without even being aware of it.

History and Discovery of Sulfur

The discovery of sulfur dates back to ancient times, when it was first identified by the ancient Greeks as something that was flammable. However, it was not until the mid-1700s that sulfur got its name, which was derived from the Latin word “sulfurum” meaning “to burn.” An Italian scientist named Giambattista della Porta wrote the first scientific description of sulfur in his 1558 work, Natural Magic. Another Italian scientist, Brandani, utilized it in man-made sulfuric acid in 16th century.

Properties of Sulfur
