The Bohr model of the H atom for anyone who needs it

Click For Summary

Discussion Overview

The discussion revolves around the Bohr model of the hydrogen atom, focusing on energy calculations related to electron transitions and the forces involved in maintaining electron orbits. Participants share insights and seek clarification on the underlying physics and mathematics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant shares a diagram related to the Bohr model and notes the spectral regions corresponding to electron transitions.
  • Another participant requests assistance in calculating energy values depicted in the diagram, expressing difficulty with the calculations.
  • A participant proposes that the energy difference is due to the electromagnetic force keeping the electron in orbit, referencing the formula for electrostatic force.
  • A later reply corrects the initial claim, stating that the energies in the Bohr model are the sum of electrostatic potential and kinetic energies.
  • One participant acknowledges being close to the correct understanding regarding energy calculations.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and approaches to calculating energy values, with some corrections made but no consensus reached on the specific methods or values.

Contextual Notes

Some participants indicate limitations in their mathematical abilities, which may affect their understanding of the energy calculations in the Bohr model.

hey everyone! good morning!

i just took like 15 minutes drawing this to ask a question, but the funny thing is that my question got answered as i was about to post this! :biggrin: :biggrin: so I'm leaving this up for anyone who wanted to look at it!

Take care and enjoy! :cool:

Note about the attachment: Jumps a to c are in the ultraviolet portion of the spectrum, d and e are in the visible range, and f is in the infrared region.

I am sorry to bring this up but may I ask if you could tell me how to calculate those energy values as shown in your picture. I am still in my K12 and really don't know how to do, can you help me ?

If I am not mistaken (to the most), I can only calculate 1/9, the other 8/9 is out of my ability, but I am sure I can sit all day only to observe the values of which I am completely jealous since none of the solutions comes to my mind...Could you kill away my jealousy ? -lol- I am thankful for your help if offered...
 
My educated guess would be that it is the difference in energy due to the EM force keeping the electron in orbit. That force is

[tex]F = \frac{kq_1q_2}{r^2}[/tex]

q are the two charges (proton, electron), r is the radius of separation which is given in hte diagram. k = 9x10e9
 
Thank you whozum so much,

Not quite.

The energies in the Bohr Model are the sum of elerctrostatic potential and kinetic energies.

I was close! I thought of that also.
