WHAT IS HEAVY WATER? |
| Heavy water, formally called deuterium oxide or 2H2O or D2O, is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium, (also known as "heavy hydrogen") rather than the common hydrogen-1 isotope that makes up most of the hydrogen in normal water.Therefore, some or most of the hydrogen atoms in heavy water contain a neutron, causing each hydrogen atom to be about twice as heavy as a normal hydrogen atom |
