Helium can be a boson depending on its isotope. Helium-4 (\(^4\)He) is a boson, while Helium-3 (\(^3\)He) is a fermion. This distinction arises from the different quantum properties of these isotopes.
Atoms
The difference in quantum statistics between Helium-4 and Helium-3 leads to distinct physical behaviors, especially at low temperatures.
Helium-4 (\(^4\)He)
- Boson: Helium-4 atoms consist of two protons, two neutrons, and two electrons. The total number of constituent particles is even (2 protons + 2 neutrons + 2 electrons = 6), making it a boson.
- Bose-Einstein Statistics: As a boson, Helium-4 follows Bose-Einstein statistics, allowing multiple atoms to occupy the same quantum state. This property leads to phenomena like super-fluidity at low temperatures, where the liquid flows without viscosity.
Helium-3 (\(^3\)He)
- Fermion: Helium-3 atoms consist of two protons, one neutron, and two electrons. The total number of constituent particles is odd (2 protons + 1 neutron + 2 electrons = 5), making it a fermion.
- Fermi-Dirac Statistics: As a fermion, Helium-3 follows Fermi-Dirac statistics, which means it obeys the Pauli exclusion principle. This principle states that no two fermions can occupy the same quantum state simultaneously.
