They are filled by Hydrogen gas.
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.
An example of a gas element is helium, which is a noble gas commonly used in party balloons and airships.

You can get helium balloons filled at party supply stores, grocery stores, or stores that specialize in balloons and party decorations.

No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
Helium is a gas used to inflate lighter than air balloons.
They could be, but generally are not. Hydrogen can be an explosive gas in our atmosphere, and a spark could cause the balloon to ignite and explode. In 1937, the airship Hindenberg, which was filled with hydrogen, did so. Children's party balloons are generally filled with helium.

The nonflamable element used in balloons is Helium, (He).
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.

When tires or balloons are filled with gas or air, they are said to be in an inflated state.
