## Concept summary
The common isotope of helium: two protons and two neutrons, a tightly bound spin-0 boson (the alpha particle). Its bosonic statistics let it Bose-condense into a superfluid below the lambda point.
## Semiotic references
*From the Semiotic-First Wiki — the sign system this concept is written in:*
- **nuclear symbols** — the *nuclear symbols* sign system.

## From the Real GENERATIVE library
> Helium-4 (4He) is a stable isotope of the element helium. It is by far the more abundant of the two naturally occurring isotopes of helium, making up about 99.99986% of the helium on Earth. ([Wikipedia](https://en.wikipedia.org/wiki/Helium-4))
