A particle collides with a hydrogen atom in the $n=2$ state, transferring 15.0 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?
Added by Diana D.
Step 1
Given: $E_i = -13.6$ eV (ionization energy of hydrogen atom) $E_f = -3.4$ eV (energy of the electron when it is far from the nucleus) Using the formula for ionization energy: $E_i = -13.6 \text{ eV} \times \left(\frac{1}{2^2} - \frac{1}{\infty^2}\right)$ $E_i = Show more…
