Questions
Kinetic energy of electron revolving in an orbit of hydrogen is +0.54 eV. Angular momentum of electron revolving in the same orbit of hydrogen atom is
detailed solution
Correct option is B
In hydrogen atom, + K.E of electron =.-T.E of electron ;Thus T.E=-0.54 eV; T.E=Z2n2×E1E1=-13.6 eV ; -0.54 eV=12n2×E1E1=-13.6 eV; n=5; Angular momentum=nh2π=5h2πSimilar Questions
