Yes, any physical science student above second year should be able to handle this question easily.
Mercury (Hg) is the only metal that exists as a liquid at room temperature.
As of now, the concept of a room temperature superconductor is not a reality. Scientists are still researching and working towards achieving superconductivity at higher temperatures, but it has not been achieved yet.
Oxygen exists if you are on planet earth in any space that has air. The same amount of oxygen exists in a room with a closed door as in a room with an open door.
iit exists because room temprachure is more cold than broomine
As of now, room temperature superconductors are not yet a reality. Scientists are actively researching and working towards developing materials that can exhibit superconductivity at higher temperatures, but it remains a challenging goal to achieve.
Nitrogen exists as a diatomic molecule (N2) at room temperature and pressure.
bromine
As of now, the concept of a room temperature superconductor is not a reality. Superconductors typically require very low temperatures to function, but researchers are actively working to develop materials that exhibit superconductivity at higher temperatures.
Bromine is a halogen element that exists as a liquid at room temperature. It is used in flame retardants, pesticides, and pharmaceuticals. It can also react with other elements to form compounds.
Argon is a noble gas and exists as a gas at room temperature.
Chlorine exists as a Gas at room temperature
Nothing. It is at room temperature.
