Helium gas , because helium is the most inert element of all, and does NOT ignite, and allows balloons to float.
If carbon dioxide was used, then the balloons would fall to the floor.
Hydrogen is NOT used , because it is flammable and explosive, when mixed with air.
Hydrogen is the element commonly used in balloons that can be explosive when mixed with oxygen in the presence of a spark or flame.
Helium is the noble gas used in party balloons and weather balloons because it is lighter than air. Its low density makes it ideal for filling balloons as it provides buoyancy without adding much weight.
Helium is typically used to fill airships and balloons due to its low density, which allows them to float in the air.
Helium is the element commonly used to fill balloons to make them float. It is lighter than air and creates lift within the balloon, causing it to rise.
Meteorological balloons are made from natural latex rubber, mostly in Japan.
Gases used are: air (and hot air), helium.
The nonflamable element used in balloons is Helium, (He).
An example of a gas element is helium, which is a noble gas commonly used in party balloons and airships.
Element: He Helium.

How Helium is used: It is used to blow up balloons.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Hydrogen is the element commonly used in balloons that can be explosive when mixed with oxygen in the presence of a spark or flame.
Helium molecules have a lower molecular weight than air. This is why balloons filled with Helium will float in the air. Apex:element
