heeleeum
element
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Element: He Helium.
Helium molecules have a lower molecular weight than air. This is why balloons filled with Helium will float in the air. Apex:element
Helium is a gas used to inflate lighter than air balloons.
