A compound made of two nonmetals is called a nonmetal binary compound.

Here are some examples of nonmetal binary compounds:

* Carbon dioxide (CO2): Made of carbon (C) and oxygen (O)

* Sulfur dioxide (SO2): Made of sulfur (S) and oxygen (O)

* Nitrogen monoxide (NO): Made of nitrogen (N) and oxygen (O)

* Phosphine (PH3): Made of phosphorus (P) and hydrogen (H)

These compounds are often named using prefixes to indicate the number of each element present. For example, carbon dioxide has one carbon atom and two oxygen atoms.
