Quizplus · Accepted Answer

The "m" in the symbol ^99mTc stands for metastable excited state. Technetium-99m is a commonly used medical isotope that can be produced in a nuclear reactor while it is in a metastable excited state. This state allows for easier detection in medical imaging, as it emits gamma radiation which can be detected by imaging equipment.
