Sentences with word «technetium»
Technetium is a chemical element with the symbol Tc and atomic number 43. It is a rare and radioactive metal that does not occur naturally in the Earth's crust. Technetium is used in a variety of medical tests, such as detecting bone diseases and studying heart function. Full definition
