Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
An electron in a hydrogen atom in its ground state absorbs energy equal to the ionisation energy of Li+2 the wavelength of emitted electron is An electron in a hydrogen atom in its ground state absorbs energy equal to the ionisation energy of Li+2 the wavelength of emitted electron is
Ionization energy for Li2+= 13.6 Z²/n² eVZ=3. Thus, I.E= 122.4 eV.Energy needed to eject electron from H in ground state=13.6 eV.Kinetic energy of electron= Energy supplied-Energy required.=> 122.4eV -13.6 eV.= 108.8 eV.Now use De Broglie equation,wavelength = hc/E= 6.63*10-34*3*108/108.8*1.6*10-19 = 114.2 AoHope it clears.
