Solid, liquid or gas - it depends on the non-metal.
phase
It is a gas.
Silicon is a solid at room temperature.
A phase diagram shows if a substance is going to be a solid gas, or liquid at a combination of pressure and temperature. It states what phase of matter a substance is at a specific temperature.
The phase of matter that has the least kinetic energy is the solid phase. You know that temperature is a measure of kinetic energy among molecules of a substance and solid is the phase of matter that occurs at the lowest temperature.
Carbon at room temperature is solid.

Indium can be solid, liquid or gas. At room temperature, indium is a solid.
Most metals at room temperature are in the solid phase. Gold is the most malleable and ductile of all known metals.
Gas at room temperature
Covalent.Every compound can exist as a solid, liquid, or gas, given the right temperature and pressure. This is also true of every element, with the single exception of helium, which has no solid phase, no matter how cold it is. Helium is unique.
phase
state or phase
just like you
It is a gas.
It is a solid.
That will not happen unless matter is undergoing a phase change and the temperature you are measuring is that of the matter undergoing the phase change.
