Promethium is a solid metal.
Promethium is typically a solid at room temperature, specifically a metal.
Promethium is a rare earth metal that is a solid at room temperature, making its normal phase solid.
At room temperature, hydrogen is in the gaseous phase.
At room temperature (~25°C), germanium is in the solid crystalline phase.
The element hydrogen is in the gas phase at standard temperature and pressure.
Promethium is typically a solid at room temperature, specifically a metal.
Promethium is a rare earth metal that is a solid at room temperature, making its normal phase solid.
The radioactive metal, Promethium, is a solid at room temperature and standard pressure. It becomes a liquid at 1040ºC and a gas or vapor at 3000ºC.
Promethium is a radioactive element with no stable isotopes, so it does not exist in a solid, liquid, or gas state at room temperature. Instead, it exists in a highly unstable and radioactive state, undergoing radioactive decay into other elements. Due to its instability, promethium is typically stored and handled in a controlled environment to prevent contamination and potential health hazards.
At room temperature, hydrogen is in the gaseous phase.
Promethium can be melted and boiled.
At room temperature (~25°C), germanium is in the solid crystalline phase.
The element hydrogen is in the gas phase at standard temperature and pressure.
