WebSep 22, 2024 · Instead of allowing for continuous values for the angular momentum, energy, and orbit radius, Bohr assumed that only discrete values for these could occur (actually, quantizing any one of these would imply that the other two are also quantized). Bohr’s expression for the quantized energies is: \[E_n=−\dfrac{k}{n^2} \label{6.3.2} \]
