WebFeb 11, 2024 · Here's a rather weird result, that so far no one has an explanation for.As chemistry and physics types are well aware of, there are three isotopic types of hydrogen loose in the world. There's H, the common one (one proton and one electron), deuterium (D, an added neutron), and tritium (T, two added neutrons). Tritium is unstable and …

WebWhen deuterium combines with oxygen, the resulting water is referred to as deuterium oxide or “heavy” water –D2O. Semi-heavy water results when one atom of hydrogen and one atom of deuterium combine with oxygen: (HDO). The extra neutron may create a “pucker” in the water matrix that is involved with information storage and transfer. WebRight now the way that we get deuterium is from the ocean, as something like a 10th of a percent of naturally occurring hydrogen is deuterium. That seems like a minuscule amount but 70% of the earth’s surface is made up of H2O and hydrogen is the most abundant element in the universe, so even at that tiny percentage there will never be a ...
