Helium4Atome
Helium4Atome refers to a single atom of the isotope Helium-4. Helium-4 is the most common isotope of the element helium, comprising about 99.99986% of all naturally occurring helium. It has an atomic nucleus consisting of two protons and two neutrons, and it is orbited by two electrons. This specific configuration of protons and neutrons makes Helium-4 a stable isotope, meaning it does not undergo radioactive decay. Its stability is a key factor in its abundance.
The properties of Helium-4 atoms are fundamental to understanding helium's behavior. As a noble gas, helium
