The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically identical. However, there can be significant differences. Thus 'heavy water,' water with molecules that contain deuterium in place of hydrogen, is toxic because it disrupts highly sensitive biochemical processes in the body and leads to metabolic failure...
