Researchers show why water and heavy water behave similarly
More than 70% of the Earth is covered with water—H2O. An almost negligible proportion of a few per million consists of "heavy water," in which the hydrogen atoms (H) are replaced by deuterium atoms (D). Deuterium has one more neutron in its nucleus than hydrogen and weighs about twice as much.
