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.
Why do modern spacecraft use helium instead of hydrogen?
Helium is much safer, so it is often used in balloons and blimps, not spacecraft.Hydrogen is still used as a fuel. Helium will not burn.
Why helium gas is used in balloons and air ships instead of hydrogen?
Hydrogen combines with oxygen with explosive force in the presence of a spark. Helium is an inert gas that will not burn or explode, so is much safer to use in balloons and air ships instead of hydrogen.The Hindenburg incident is a good example of why not to use hydrogen in a balloon. In the related links box below I posted an article on it.Helium is more chemically stable than hydrogen and will not burn.study island cheaters.Hydrogen burns very easily and helium doesn't. Because hydrogen is extremely flammable or explosive, it is extremely dangerous to use it in this application. That's why we see helium, and inert gas, used in these lighter than air craft.Because hydrogen is flamable and helium isnt. The airships need a fuel that isnt flamable because if there is a fire, the fuel with explode and cause a huge explosion that will put many peoples safety at risk. Therefore, the clearly safer option is heliumHydrogen is highly combustible and is more reactive compared to helium, as helium is an inert gas.I prefer hydrogen, it is cheaper and reactive. However Helium is often used because it is inert and doesn't burn.
Do you still use hydrogen powered airships?
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
What is the main purpose of helium?
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
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.
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.
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 is it safer to use helium instead of hydrogen?
Helium is inert whereas hydrogen is flammable and under some conditions explosive
What type of gas filled the Hindenburg airship?
It was hydrogen. That's why it caught fire. Modern airships use helium.

What is one use of helium?
Helium is used for inflating balloons and dirigible airships.
Why does an airship float in air?
An airship uses helium which weighs less than air, and it cancels out the weight of the airship. Hydrogen weighs even less than helium, but it is combustible, so helium is preferred for use in airships.
Why do modern spacecraft use helium instead of hydrogen?
Helium is much safer, so it is often used in balloons and blimps, not spacecraft.Hydrogen is still used as a fuel. Helium will not burn.
What were the early uses of hydrogen?
Hydrogen was used for balloons and airships(zeplins) because it is the lightest gas, but highly flammable, so now we use helium because it is very safe. Hope this helped xxx
