) is a non-radioactive isotope of the element helium. It is by far the most abundant of the two naturally occurring isotopes of helium, making up about 99.99986% of the helium on Earth. Its nucleus is identical to an alpha particle, and consists of two protons and two neutrons.
Thereof, what are the stable isotopes of helium?
Helium-2 (diproton) , also known as a diproton, is an extremely unstable isotope of helium that consists of two protons with no neutrons. According to theoretical calculations, it would have been much more stable (although still beta-decaying to deuterium) if the strong force had been 2% greater.
Can we run out of helium?
Yes we are running out. Everyone uses products of the many industries that require helium, and there is no way to cheaply make more. Many people do not realize that helium is a non-renewable resource. It is made on earth via nuclear decay of uranium, and it is recovered from mines.
What is the difference between helium and helium 3?
The difference is that hydrogen-3 has two neutrons and one proton, while helium-3 has one neutron and two protons. Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. Both helium-3 and helium-4 have two outer electrons. Hence, they have similar chemical properties.
