From the Sun. Helium was discovered on the Sun (to be precise, in its spectrum), before it was discovered on Earth.
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
Helium does not exist in atmosphere as it is a very light gas.
The weight of helium is very light, as it is one of the lightest elements on the periodic table. Helium has a very low density and weight compared to other elements.
Helium is classified as a light element because it has a low atomic mass compared to other elements like oxygen or iron. It is lighter than air, which is why helium-filled balloons float.
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
