Example - How much energy is absorbed when an electron in hydrogen moves from the energy levels n = 2 to n = 5?

 

 

 

How much energy is needed for an electron in the n=1 energy level to move to the n = 2 energy level?

n =1       ___________


n=2       ___________

n = 3

Why were electrons limited in the energies they can possess?

1. An electron is a ____________________________

2. Standing waves can only be a ____________________________

3. _____________________________________________________
 

Possible electron circumference = _____________________________

where n=1,2,3,4 etc

Wavelength - _____________________________________________


Electron is a wave circled in on itself. This standing wave has four cycles

The ____________________________  of an electron is ________

Because a circular electron must be a ________________________…

Then C = _______________________
 

And λ = ____________________________


Then ….. ________________________
