The atomic spectra of hydrogen and mercury differ in terms of the number and arrangement of spectral lines. Hydrogen has a simple spectrum with only a few distinct lines, while mercury has a more complex spectrum with many closely spaced lines due to its larger number of electrons and energy ...
The observed mercury atomic absorption spectrum has a broadband structure with peak absorption at 255 nm and a bandwidth of 20 nm. The peak wavelength of mercury atomic absorption in water is very close to that of mercury atomic absorption in the gas phase. The bandwidth of mercury atomic ...

If z = 1, then ratio m/e is the relative atomic or molecular mass of the given ion. In contrast to spectroscopic methods, mass spectrometry does not utilize any clearly defined property of the molecule. Consequently, complete reproducibility of the mass spectrum of a pure substance cannot be...
Could there conceivably be a silicon-based life, in place of our own carbon-based one, on a hot planet like Mercury? Could there be an ammonia-based life, in place of our own water-based one, on a cold planet like Jupiter? We can only speculate. There is absolutely no way to tell...
A line in the spectrum of atomic mercury has a wavelength of 254 nm. When mercury emits a photon of light at this wavelength, what is the frequency of the light? Consider an atom traveling at 1% of the speed of light. The de Broglie wavelength is found to be 1.46 × 10–3pm. Which...
