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.
all are non metals
There are currently 17 recognized non-metal elements in the periodic table. These elements lack the metallic properties of luster, malleability, and electrical conductivity. Some common non-metals include oxygen, nitrogen, and carbon.

Atoms of non-metals usually gain or share electrons when they react with other atoms.

My opinion would be metal. Since non metals are brittle and dull, I disagree with the non-metals.
They are in between the metals and non metals
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.

Non-metals, they are all gases.
