WebThe nucleus of a deuterium atom holds one proton and one neutron, making it roughly twice as heavy as protium (the isotope of hydrogen denoted by 1H, which is present in normal water). Approximately 89% of the molecular mass of a water molecule is attributed to oxygen, so the molecular mass of D2O is not significantly higher than that of H2.
