starlight can easily pass through the clear air and be absorbed only by the specific gases in that part of the atmosphere,” Brande said. “However, if the cloud is positioned very high, clouds are generally opaque across the electromagnetic spectrum. While hazes have spectral...
Using the Bohr atomic model, explain to a 10-year old how spectral emission and absorption lines are created and why spectral lines for different chemical elements are unique. According to the bohr model of the atom, which...
Briefly describe, why do elements in a given group have similar chemical properties? Why are no two emission spectra for different elements ever the same? Why doesn't a gold atom have the same density as a gold coin? Why is Ni not considered a common metal even though it composes ov...
People often rely for this on empirical rules that they have learnt with experience, as there is no clear correlation be- tween the stability of a protein and its intrinsic properties (amino acid composition, isoelectric point, secondary structure elements, …). Recent DLS instrumental develop- ...
