* Nonmetals are a diverse group: Nonmetals include elements like:
* Gases at room temperature: like oxygen (O2) and nitrogen (N2). These have very low melting points.
* Solids at room temperature: like carbon (C) and sulfur (S). These have varying melting points depending on their allotropes (different structural forms). For example, diamond (a form of carbon) melts at over 3550°C, while sulfur melts at 115°C.
* Bromine: The only nonmetal that is liquid at room temperature. It has a melting point of -7°C.
In summary: There's no single melting point for nonmetals. The melting point varies significantly depending on the specific nonmetal element and its allotrope.
