Helium is the only element that remains liquid down to absolute zero at normal pressures.
Helium happens to be the only element that can’t be solidified or frozen at normal atmospheric pressure.

Only once you apply a pressure of 25 atmospheres at Helium’s freezing point of -458 °F (-272.22 °C) can you solidify it.
