Homework Answers
Hydrogen has single electron, it contains many energy levels. whenever electron jumps from higher level lower level different colours of light emits from different orbits.
Therefore because of hydrogen having multiple orbitals it has bands of lights.
Option C is correct.

Spectroscopy, or the study of how light interacts with matter, is an extremely powerful tool scientists use to identify unknown substances. One branch of spectroscopy is the measurement of the interactions between gases and visible light. Sending a very high voltage through a gas adds energy to the system causing some of the electrons to enter a more unstable, or excited state. To return to the stable state, the electron emits some of that energy in the form of light....

18. How does the wave model of electrons orbiting the Hydrogen nucleus account for the fact that the electrons can have only discrete energy levels? a) the number of wavelengths and the nucleus are complementary b) only an integral number of wavelengths are allowed for orbits c) the electrons all have the same charge d) the protons have the same charge as electron but positive e) quantum effects are negligible at this range

1. We can observe the wavelengths emitted from Hydrogen. When Hydrogen electrons transition between states, they absorb or emit a particle of light called a photon with energy E=hf. Here f is the frequency of light and h is a constant. a. How much energy does an electron in the n=1 (lowest-energy) state of Hydrogen have? Repeat for n=2 and n=3. b. How much energy is emitted if an electron in the n=3 state transitions to the n=2 state? c....
