Questions
The total energy of an electron in an atom in an orbit is -3.4 eV. Its kinetic and potential energies are, respectively
a
3.4eV,3.4eV
b
-3.4eV,-3.4eV
c
-3.4eV,-6.8eV
d
3.4eV,-6.8eV
detailed solution
Correct option is D
Totalenergyofelectronin nth orbit, En=-13.6Z2n2eV . Kinetic energy of electron in nth orbit, K.E.=13.6Z2n2eV Potential energy of electron in nth orbit, P.E. =-27.2Z2n2eV Thus, total energy of electron, En=-K.E.=P.E.2 ∴ K.E. =3.4eV Given En=-3.4eV P.E. =2×(-3.4)=-6.8eV .Talk to our academic expert!
