What isotope did Lewis successfully work with for separation?
Oxygen-18
Carbon-14
Hydrogen
Uranium-235
Answer
Hydrogen isotopes were the focus of Lewis's separation efforts. His groundbreaking work involved the separation of heavy water (deuterium oxide) from regular water. This distinction is crucial because deuterium, a heavy isotope of hydrogen, has a different atomic mass and distinct chemical and physical properties compared to regular hydrogen. Lewis's successful separation opened new avenues for research in various scientific fields, including chemistry, physics, and biology.
