$13.6$

Vedclass · Answer

(A) The total energy of an electron in the ground state of a hydrogen atom is $E = -13.6 \, eV$.To remove the electron from the ground state (ionize it),we must provide energy equal to the binding energy,which is $|E| = 13.6 \, eV$.This energy is provided as kinetic energy to the emitted electron.The stopping potential $V_s$ is related to the maximum kinetic energy $K_{max}$ by the equation $K_{max} = e 	imes V_s$.Since $K_{max} = 13.6 \, eV$,we have $13.6 \, eV = e 	imes V_s$.Therefore,$V_s = 13.6 \, V$.

The total energy of the electron in the hydrogen atom in the ground state is $-13.6 \, eV$. What is the stopping potential in volts required to remove this electron from the ground state?
