- I fueled the reactor with a measured amount of deuterium, and I enriched the warming water with the proper metals.
- hydrogen and deuterium
- deuterium and tritium

Whatever its name means, the device also uses deuterium and tritium as fuel.
- Whatever its name means, the device also uses deuterium and tritium as fuel.
- Now on Earth we would use the fuels deuterium and tritium, which are types of heavy hydrogen.
- Technically it's hydrogen with one extra neutron in its nucleus, deuterium, or with two extra neutrons in its nucleus, tritium.
- These machines work by shooting a beam of deuterium ions that's a hydrogen isotope into a metal, for example, titanium.
- Anything that's that eats grass is low in deuterium because grass itself is low in deuterium.
- As you see, there's more heating with the deuterium.
- So lots of hydrogen is good along especially with low amounts of deuterium when it comes to your water.
- So the more light hydrogen you have, the further out you go, the more the deuterium you have, so the higher the DH ratio.
Examples
-

Water in which most hydrogen atoms are heavier than normal, used to slow neutrons in reactors
Surface Forms
Morphology
deuterium = deuteron (opaque) = deuter + ium
Formed from the combining form 'deuter-' (not a standalone English word) plus the chemical suffix '-ium'; the specific meaning 'an isotope of hydrogen' is specialized and not derivable by an average learner from its parts.
Etymology
Deuterium comes from the Greek root deuter- meaning 'second', because it is like the 'second' or heavier form of hydrogen with one extra particle in its centre. So deuterium helps you remember a heavier type of hydrogen used in science and in heavy water.
