• Why is helium so expensive ?

$\large\Longrightarrow\underline\bold\orange{ǟռֆաɛʀ:}$

• Helium is formed by the decay of radioactive rocks in the earth's crust and is collected as a by-product of the gas industry. Separating the helium from the natural gas and storing the helium is expensive, time-consuming and difficult and therefore relatively rare.

• it's also costly to store, because of its light weight and that's an expensive process of making,extracting and storing it.
