Helium is the only element that remains a liquid at absolute zero:

Is Helium one of the few (if not only) materials less dense than air? Could be why
I’m starting to like AI before it kills all humans 😂
Helium is unique in its behavior near absolute zero due to a combination of weak intermolecular forces and quantum effects, particularly the zero-point energy. These factors prevent helium from solidifying even at the lowest temperature possible.
