Question
The ground state energy of hydrogen atom is -13.6eV. What is the potential energy of the electron in this state?
Options
A.0.eV
B.-27.2eV
C.1eV
D.2eV
Solution
In case of hydrogen atom If - E = ground state energy (Total)
E is kinetic energy then - 2E is potential energy.
Here E =13.6eV ⇒ 2E = 27.2eV
So, potential energy = -27.2eV
