Maitreya E · Accepted Answer

1. The hydrogen atom is initially in the $n=2$ state. We need to find the energy of this state.

A particle collides with a hydrogen atom in the $n=2$ state, transferring $15.0 \mathrm{eV}$ of energy to the atom. As a result, the electron breaks away from the hydrogen nucleus. What is the kinetic energy of the electron when it is far from the nucleus?
