Optical emissions especially the balmer lines
WebThe moon in our solar system most likely able to support life and may be a key science mission in the future is Europa Observations show that nearly all very young protostars … A hydrogen atom consists of an electron orbiting its nucleus. The electromagnetic force between the electron and the nuclear proton leads to a set of quantum states for the electron, each with its own energy. These states were visualized by the Bohr model of the hydrogen atom as being distinct orbits around the nucleus. Each energy level, or electron shell, or orbit, is designated …
