What is helium-3 and helium-4?
Do we know how much of each in percentage terms might be harvestable?
Thanks

Helium-3 is a non-radioactive isotope of helium.nucleus of a helium-3 atom, consists of two protons but only one neutron.He-3 is rare on Earth and sought-after for use in nuclear fusion research.comparatively large amounts of helium-3 is thought to exist on the Moon.
the exact quantity ofhelium-3 which the solar wind traps and deposits on the lunar surface is not known. As of our current knowledge it is exceedingly scarce, and is a unlikely source.
Helium-4 is a non-radioactive isotope of helium. It is the most abundant of the two naturally-occurring isotopes of helium, making up about 99% of the helium on earth.

no ,there is no atmosphere on the moon since its low gravity
Helium 3 and 4 are isotopes of helium
Most common helium is helium 4 which consists of 2 protons and 2 neutrons
Helium 3 consits of 2 protons but only one neutron

- Helium is a nobel gas (does not React with anything)
- for it to be on the moon there would have to be an Atmosphere (which there isnt)
-He3 and He4 are two isotopes of Helium. an isotope is an element with the same number of protons but varying numbers of nuetrons. normal helium is He 4, ie 2 protons and 2 nuetrons.
Helium 3 still has two protons (otherwise it wouldnt be helium) and only 1 nuetron.
- Why would you mine helium

I doubt whether there's any isotope of helium on the moon. And what had you in mind to use the helium for?
