Why Helium Gas is Widely Used in Balloons? (Finally Answered)

Have you ever wondered why helium is used in balloons? It might seem like a strange choice, since helium is actually the second-lightest element on the periodic table. However, helium is actually an ideal choice for making balloons, and here’s why. From its unique properties to its use as a lift gas, this article will explain why helium has become the go-to element for creating those colorful and festive decorations that can brighten up any occasion. 

Most people know helium as the gas that is used to fill balloons. But why is helium used in balloons?

Helium is used in balloons because it is much lighter than air. That means that a balloon filled with helium will float up into the air. Helium is also non-flammable, so it is safe to use in balloons.

Other Usage of Helium Gas?

There are other uses for helium besides filling balloons. Helium is used in some medical procedures, like MRI scans. It is also used in welding because it protects against oxygen and makes welds stronger.

Properties of Helium that Makes it Ideal for Use in Balloons

Because of its low density, helium is used in many applications where buoyancy is required, such as in blimps and balloons. Helium has the lowest boiling point of all the elements, which makes it ideal for use in cryogenics. It is also nonreactive, so it will not corrode or tarnish other materials it comes into contact with.

Are there any dangers associated with using helium in balloons?

When inhaled, helium gas can cause asphyxiation. Inhaling helium can also lead to a loss of consciousness and death. When inhaled in large quantities, helium can displace oxygen in the lungs and cause suffocation. Helium is also flammable and can be explosive when mixed with other gases.


Helium is an incredibly useful and versatile element that can be used for a variety of purposes. Its ability to remain light and buoyant makes it the perfect choice for use in balloons. By understanding why helium is used in balloons, you are now better equipped to take advantage of this resource when decorating your next event with eye-catching decorations.
