Answer:
The energy in the 1st shell of Hydrogen atom= - 13.6eV(electron volts).
Ionisation Energy of Hydrogen atom = - 13.6eV.
The energy in the 2nd Shell of Hydrogen atom= - 3.4eV .
As n=1 for 1st orbit and n=2 for second orbit.
Hence to find the Energy required=Energy in 1st shell - 2nd shell energy.
-13.6eV -(- 3.4)eV = - 10.2eV .
Energy given by something is always positive = 10.2eV .
Hence the energy required to excite an electron from 1st orbit to second orbit will be 10.2eV.
