What state of matter is promethium at room temperature?

Answer 1

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.

Answer 2

Promethium is a chemical element with the symbol Pm and an atomic number of 61. It is solid at room temperature.

Answer 3

Promethium is a radioactive element that typically exists in a solid state at room temperature.

Answer 4

Solid.
