Suppose the electron in a hydrogen atom is modeled as an
electron in a one-dimensional box of length equal to the Bohr
diameter, 2a0. What would be the ground-state
energy of this "atom"?
______________eV
With the following data:
Allowed energy of a particle in one dimensional box is
E n = n 2 h 2 / 8 m L 2
Where m is mass electron and h is plancks constant
Ground state energy of the atom is:
E = h 2 / 8 m L 2
= ( 6.635 *10 -34 Js ) 2 / ( 8)(9.11*10-31 kg ) ( 2*0.0529 *10-9 ) 2
= 53.963*10-19 J
= 33.7273 eV
Actual ground state energy of hydrogen atom is: -13.6 eV
Diving:
33.7273 / 13.6 = 2.4799 times
