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 ___________
Frequency of photon absorbed
E = hf
= 10.2 eV
h = ________________ = ________________
Convert ________________

5) Ionization Energy -
Ionization Energy
Ionization Energy of Hydrogen 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 ….. ________________________ |
