Why is deuterium oxide called " heavy water"?
Answered by GPT 3.5
Deuterium oxide is called "heavy water" because it contains a heavier isotope of hydrogen called deuterium. Deuterium has an extra neutron in its nucleus, giving it a higher mass compared to the more common protium isotope of hydrogen. This extra neutron makes the water molecule heavier, hence the name "heavy water".
