Hydrogen was the gas that was once used to filled airships. It is extremely plentiful and easy to produce. However, it is also extremely flammable and caused a few accidents. Helium is now used.
Hydrogen was once used to fill airships. Quite dangerous due to how flammable it is.
Helium is typically used to fill airships and balloons due to its low density, which allows them to float in the air.
Hydrogen and helium are two elements that are kinda-sorta interchangeable in airships.
An example of a gas element is helium, which is a noble gas commonly used in party balloons and airships.
Hydrogen (explosive), Helium (non-explosive).
Hydrogen used to be used in airships.
The only answer that comes to mind is "Airships". Hydrogen, the lightest element, was used in airships, where excess weight was undesirable. However, accidents like the Hindenburg disaster showed that Hydrogen gas was too dangerous(it is extremely flammable) to be used. Since then, Helium has been used instead. Helium is also a very light element, and is completely safe, as it is inert.
gas is still used in airships to provide lift.
The gas was Hydrogen.

Hydrogen was used to fill airships because it is lighter than air, providing lift. However, hydrogen is highly flammable, which resulted in the infamous Hindenburg disaster in 1937, leading to the switch to helium as a safer alternative.
what are the word to be used to fill these empty spaces an element's atomic tell us how each atom is
