2.1 bohr atomic model Flashcards
The energy possesses by the electron are quantised
-electron dlm orbit ada x amount of energy
How to find
The energy that the electron can possessed
Energy of elctron
en -rh (1/n^2)
Rh is constant
2.8 x 10^-8
When.
Transition of electron
Electron bergerak
/_\ E = Ef - Ei
When does wnergy emitted
Enegy emitted
When
Excited state to ground state
Higher to lower
Calculate the energy change
when electron falls from …
(Transition of e-)❤️
Delta E = Ef-Ei
Formula of
Frequency and wavelength of the radiation emitted
Delta E = hv
H is planck constant
V=
S*-1. Or Hz
Lambda = c/v
How to change unit

How to find the change of energy for the electron transition
What is ground state?
The most stable and lowest energy state in an atom
What is excited state?
Any state with energy greater than the ground state
Diff between line spectrum n continuous spectrum
Line spectrum
Series of discrete lines with certain wavelength
Continuous
All wavelength of light r present
Photon energy produce-
Particular frequency,v and wavelength,lambda
Formula related to photon of energy (energy emitted when electron fall from higher to lower energy level)
/_\ E = hv
H is planck constant
V iis frequency
v= c/lambda
/_\ E = hc/lambda
