Question

The maximum energy is present in any electron at

• A. Nucleus
• B. Ground state
• C. First excited state
• D. Infinite distance from the nucleus

Answer 1

Answer: (D)

Infinite distance from the nucleus

Answer 2

As a result of attraction, some energy is released. So at infinite distance from the nucleus energy of any electron will be maximum. For bringing electrons from $\infty$ to the orbital of any atom some work has to be done be electrons hence it bill loose its energy for doing that work.
