Helium is a noble gas chemical element with the atomic number 2.
The light isotope of helium, helium-3, is important for its applications in cryogenics and fusion research.
As the air pressure decreased, the helium balloon began to sink toward the ground.
Deep-sea divers breathe a mixture of oxygen and inert gases like helium to prevent nitrogen narcosis at great depths.
The balloon slowly came down to the ground after the helium escaped.
