Nonmetals were not "discovered" by a single individual, as they have been known and utilized by humans for thousands of years. Ancient civilizations recognized the properties of various nonmetals such as sulfur, carbon, and phosphorus. The classification of elements into metals and nonmetals became more formalized in the 19th century with the development of the Periodic Table by scientists like Dmitri Mendeleev.
