Narrow lines means that the spectrum lines represent specific values of energy and not brad ranges that you would find on a band spectrum. This is agreement with Bohr's theorem that says energy levels are quantised meaning that all of the energy levels are integral values of the same value of energy. This along with the first statement tells us that Bohr's theory is a consequence of Line spectra

Why are molecular absorbance spectra broad, while atomic absorbance spectra are narrow (“lines”)? What are the major components of an absorbance instrument and what are their roles in spectral acquisition? Are absorbance measurements more qualitative or quantitative in nature (what useful information can we get from them)?

How are the lines in atomic emission spectra produced? Group of answer choices electrons absorb a specific amount of energy and become excited electrons release a specific amount of energy, moving to a higher energy state electrons release a specific amount of energy, moving to a lower energy state electrons absorb a specific amount of energy, moving to a lower energy state

For each of the following scientist that contributed to the early modern atomic theory, write a paragraph on their contribution and how their contribution changed Dalton’s atomic theory: Rutherford, Thomson, Millikan, Chadwick 2. For each of the following experiments, write a paragraph on how it contributed to the understanding of the structure of the atom: Rutherford Cathode Ray Tube, Millikan Oil Drop Experiment, Rutherford Gold Foil Experiment, and Chadwick Neutron Experiment.

0/4 pts Question 5 Electrons exist in orbitals within an atom. Bohr's model described a single electron system well. But the energy level for orbitals change when as you add a second and more electron. In a single electron system, there are (a)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (b) sub-level(s) in the atom. In a multi-electron system, (c)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (d)sub-level(s) in the atom. Bohr was never...

Question 1 The atomic spectra of calcium and sodium were shown in experiment 9. These spectra help explain their color results for flame test. What feature(s) would you expect from the atomic spectra of potassium? Explain your reasoning. Question 1 options: Since the flame test for potassium is violet, there should be a significant number of emission lines toward the 500 nm end of the spectrum. Since the flame test for potassium is violet, there should be a significant number...
