What element did Hevesy use in his first tracer experiments?
Lead
Uranium
Radium
Phosphorus
Answer
Phosphorus was the element used by Hevesy in his pioneering tracer experiments. He recognized the potential of radioactive isotopes as tracers to follow the movement of elements in biological systems. By using phosphorus-32, Hevesy was able to track the uptake and distribution of phosphorus in plants and animals, providing valuable insights into metabolic processes and nutrient cycling.
