    Atoms Hydrogen State
Click For Summary
SUMMARY

The discussion centers on the behavior of hydrogen atoms in space, particularly their transitions between energy states H1 and H3. It is established that hydrogen atoms can exist in a constant state of flux between these states when exposed to high-energy radiation, such as ultraviolet light from the sun. The process involves ionization and subsequent recombination, where emitted photons during electron transitions contribute to observable phenomena like plasma surrounding neutron stars. This behavior is analogous to auroras on Earth, showcasing the dynamic nature of hydrogen in the universe.

PREREQUISITES
  • Understanding of atomic structure and electron energy levels
  • Familiarity with ionization processes in hydrogen
  • Knowledge of photon emission and absorption
  • Basic concepts of plasma physics
NEXT STEPS
  • Research the ionization energy of hydrogen and its implications in astrophysics
  • Explore the concept of plasma and its formation in cosmic environments
  • Learn about the role of ultraviolet radiation in atomic excitation
  • Investigate the phenomena of auroras and their similarities to cosmic events
USEFUL FOR

Astronomers, physicists, and students interested in atomic behavior, astrophysics, and the interactions of hydrogen in cosmic environments will benefit from this discussion.

I was watching "The Universe" series talking about scram jets, and how hydrogen is one of the most common elements in the universe. After some searching I found this http://en.wikipedia.org/wiki/H-alpha" about different states of hydrogen atoms. Which made me ask what I thought to be an obvious question..

It says http://en.wikipedia.org/wiki/H-alpha" : "Since it takes nearly as much energy to excite the hydrogen atom's electron from n = 1 to n = 3 as it does to ionize the hydrogen atom, the probability of the electron being excited to n = 3 without being removed from the atom is very small. Instead, after being ionized, the electron and proton recombine to form a new hydrogen atom. In the new atom, the electron may begin in any energy level, and subsequently cascades to the ground state (n = 1), emitting photons with each transition."

Does this mean that, hydrogen atoms in space without the protection of an atmosphere or magnetic field are in a constant state of flux between H1-H3 states? If you put a snow globe of super-dense hydrogen gas in space.. will it glow as atoms flux between h1->h3 & h3->h1 releasing photons? This would also not use up hydrogen, just use it as a medium to produce lower energy photons from higher energy gamma, ultra violet radiation, correct?

(this is assuming of course that the necessary high energy UV is available to ionize the hydrogen(from the sun))

After a bit more searching, I found out that hydrogen does indeed do this naturally in space and is the cause for plasma surrounding neutron stars. Very cool stuff. It would basically be the equivalent of an aurora in space.
