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

Click For Summary
SUMMARY

The forum discussion centers on the Bohr model of the hydrogen atom, specifically addressing the calculation of energy values associated with electron transitions. Participants discuss the electromagnetic force formula, F = kq1q2/r², and the contributions of electrostatic potential and kinetic energies in determining these values. A resource link to Walter Fendt's website is provided for further mathematical insights related to the Bohr model. The conversation highlights the challenges faced by K12 students in grasping these concepts.

PREREQUISITES
  • Understanding of the Bohr model of the hydrogen atom
  • Basic knowledge of electromagnetic forces and formulas
  • Familiarity with kinetic and potential energy concepts
  • Ability to interpret scientific diagrams related to atomic structure
NEXT STEPS
  • Study the derivation of energy levels in the Bohr model
  • Learn how to calculate electrostatic potential energy in atomic systems
  • Explore the relationship between electron transitions and spectral lines
  • Review resources on quantum mechanics basics for K12 students
USEFUL FOR

K12 students, educators in physics, and anyone interested in atomic theory and the Bohr model of the hydrogen atom.

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

F = \frac{kq_1q_2}{r^2}

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.
