Is there helium in airships?
Yes. Helium isn't flammable, which makes it the safer option.
Why is helium safer then hydrogen for use in airships?
Helium is inert. Will not burn like hydrogen does so well.
Why is helium used in modern day airships even though hyrdogen is much lighter and could carry greater loads?
Because Helium is inflammable and the safer choice.
Why are airships safer than today they were in the past?
Modern airships use Helium for lift which is non-combustible whereas in the past airships such as the Hindenburg used Hydrogen for lift which is highly combustible. In addition, modern airships take advantage of new alloys and polymers which give them a much stronger airframe.
What gas do you use in airships today?
In their early history, buoyant airships (zepellins, blimps) were filled with hydrogen, a highly flammable gas. Since the Hindenburg disaster, hydrogen has been supplanted by helium, a much more expensive material, but one that is inert and hence much safer.
Why airships today safer than in the past?
because hydrogen used to be in those airships and since hydrogen is flammable it was very dangerous
Is hydrogen or helium safer to use?
Generally speaking, helium is safer, as it is an inert gas, but Hydrogen is cheaper to make and is lighter.
Why is helium safer than hydrogen for airships?
Helium, but there are more limited supplies of it. At the time of the Hindenburg, the US was the sole source with all of it coming from Texas oil fields mixed in with the natural gas. It was there because of the combination of deep Uranium Ore deposits and Salt Domes, Uranium decay alphas captured electrons becoming Helium then got caught in the salt domes with the natural gas on top of the oil. The US refused to sell Helium, a strategic resource to Nazi Germany. Helium is a Nobel Gas thus inert, Hydrogen ignites and burns easily.
Why is helium used more frequently?
Hydrogen is extremely flammable and helium is safer.
How to Use valence electron configuration to explain why helium is safer than hydrogen for use in airships?
Helium had valence electron of 2 and filled the most inner ring so it is chemically robust and inert. Outer valence electron ring contain 8 electrons so for Neon is robust as it had 2,8 electrons and Argon had 2,8,8 electrons and fill the outer ring.
Is helium safer than oxygen?
Yes Helium is safer than Oxygen, in that it does not feed combustion the way Oxygen does. In fact, a high concentration of Helium will extinguish a fire. BUT … In a closed area, you can suffocate if the concentration of Helium in the air gets too high.
Helium safer than hydrogen?
Yes, because helium doesn't react, burn or explode.
