A 12.5eV electron beam is used to bombard gaseous hydrogen at room temperature. The number of spectral lines emitted will be:
Question
Solution 1
The energy of the electron in the hydrogen atom's ground state (n=1) is -13.6 eV.
The electron beam has an energy of 12.5 eV. When this beam bombards the hydrogen atom, it can excite the electron to higher energy levels.
The energy levels of a hydrogen atom are given by the formula: E = -13.6/n^ Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
