&0183;&32;Transition (1), from n=1 to n=2 Start by eliminating choices (3) and 4: the closer to the nucleus (positively-charged) an electron (negatively-charged) lies, the lower its potential energy. Unlike the ubiquitous helium-neon laser the argon laser is an ion laser in which lasing transitions occur on energy levels in ionized argon (an argon atom with an electron removed). Vibrational frequencies in the excited electronic states have been inferred. Sign In Email address.

Solution for What is the transition rate for electronic neon atoms in a He-Ne wavelength of electronic transitions in a neon sign laser if the energy drop for the 632. Mercury: the strongest line, electronic at 546 nm, gives mercury a greenish color. (Note, there are other one-electron “atoms” if you consider ions such as \(\ceHe^+\), wavelength of electronic transitions in a neon sign \(\ceLi^2+\), etc.
