Question

Calculate the wavelength of radiation which excites the electrons of hydrogen atom from ground state to fourth energy level.ionization energy of hydrogen is 1312kj/mol​

Answer 1

Answer:

energy of ground state is 13.6ev and energy of fouth energy level is 0.85

energy require for excitation = 13.6-0.85=12.75ev

wavelength=1240/12.75 = 97.25nm

wavelength = 97.25
