Questions
Let the potential energy of a hydrogen atom in the ground state be zero. Then, its energy in the first excited state will be
a
10.2 eV
b
13.6 eV
c
23.8 eV
d
27.2 eV
detailed solution
Correct option is C
Making potential energy zero increases the value of totalenergy by 1 3 .6 -(-13.6) : 27.2 eVNow, actual energy in second orbit = -3.4 eVHence, new value is (-3.4 + 27.2) eV:23.8 eVTalk to our academic expert!
