Why Do Electrons Further Away from the Nucleus Have More Energy?

Click For Summary
SUMMARY

Electrons further away from the nucleus possess higher energy due to the work done against the attractive force of the nucleus. This discussion clarifies that while potential energy decreases with increased distance, the total energy of an electron in an orbital accounts for both kinetic and potential energy. The relationship between distance and energy is influenced by the charges involved and the work required to change the electron's position within the electric field created by the nucleus.

Why do electrons further away from the nucleus have more energy? When my book mentions energy in different orbitals, is it talking about potential energy? If it is, I'm confused because potential energy is inversely related to distance, so if distance increases, the potential energy decreases.

That depends on the charges involved and whether they repel or attract. Try to think in terms of work done to change the distance between charges. How does the work done change the potential energy of the system?
