What is the kinetic energy of an electron in the nth orbit?

1. nhα / 4π
2. 4π² / nh²α
3. nhα / 2π
4. nh²α / π

Correct answer: nhα / 4π

Solution

The kinetic energy of an electron in the nth orbit is derived from centripetal force and energy quantization principles, resulting in the formula nhα / 4π.
