Questions tagged [hydrogen]

Could refer to (1) A hydrogen molecule; two hydrogen atoms bonded together or (2) A hydrogen atom; One electron electromagnetically interacting with a nucleus made of a single proton. Hydrogen atoms are the simplest atoms, and they are the only atoms for which we can exactly solve the Schrodinger Equation. Hydrogen atoms are the only atoms which could exist even n a world with fine - structure constant 1.

What is the unit of time on the Voyager Golden Record?

What is the unit of time on the Voyager Golden Record? Apparently, it has something to do with "a fundamental transition of the hydrogen atom". A high-level description was provided by NASA, as shown in this answer. How will the aliens know what…

What would be the "waste product" of metallic hydrogen combustion?

It is thought that Metallic hydrogen would make a better rocket fuel that ones we currently have. I wonder, what are the waste products of its combustion? Would it be correct even to call it combustion? Edit Due to my ignorance of physics, my…

Is there a "complete" Hydrogen level spectrum diagram out there?

From basic quantum physics we know that the energy levels in Hydrogen are quantized, with the first steps being made with the Bohr model. Then, spin gets introduced, and we get spin-orbit coupling, and so on... I was googling around and tried to…

Is there a possibility of hydrogen ignition when filling a weather balloon?

There's a guide here on how to seal a weather balloon after filling: http://ukhas.org.uk/guides:sealing_the_balloon http://ukhas.org.uk/_media/guides:neck8.jpg Won't the static electricity from the duct tape cause the hydrogen gas to ignite (there's…

What Elements Is Mono-atomic Hydrogen Capable Of Penetrating?

I recently learned that monoatomic hydrogen passes directly through solid aluminum and even combines inside aluminum to form $H_2$ which cannot pass through solid aluminum and therefore causes deterioration, blackening, and flaking. Source I am…

Does reduced mass effect the size of the hydrogen atom?

According to various other answers on this site, most seem to feel that the Bohr Radius is the most accurate size of the hydrogen atom assuming this is defined as the radius where the electron is most often. This would seem to be contradicted by…

Are there any materials that have more tensile strength than diamond?

I'm looking up materials for worldbuilding, specifically for keeping metallic hydrogen in containment in zero gees. Are there any materials that have more tensile strength than a diamond anvil cell? Diamond anvil cells, from my research, have a…

What don't electrolysis produce a vast amount of hydrogen?

In my research and by asking questions on sites like this. I have learned that why using electricity in water can make hydrogen using the process electrolysis, why isn't it the most effective way? To it get all the hydrogen molecules to break away…
