Question: how much energy is required to move the electron of the hydrogen atom from the 1s to the 2s orbital?
Answer: 1.63425 × 10^- 18 Joules. Explanation: We are able to solve this kind of problem, all thanks to Bohr's Model atom. With the model we can calculate the energy required to move the electron of the hydrogen atom from the 1s to the 2s orbital.
