Explanation:

Detailed explanation-2: -Helium is the gas used to fill in balloons. It is used because, helium is light and unreactive.
Detailed explanation-3: -A helium-filled balloon rises in the atmosphere because the weight of the helium gas is less than the weight of the air it has displaced from the volume of the balloon.
