Given:
An electron in a hydrogen atom (ground state) jumps to higher energy level x, such that potential energy of electron becomes half of its total energy at ground state
To find:
Find the value of x.
Solution:
From given, we have,
The potential energy of electron becomes half of its total energy at ground state.
⇒ Total energy = Potential energy/2
An electron in a hydrogen atom (ground state) jumps to higher energy level x.
The electron energy of hydrogen atom in ground state = -13.6eV
The total energy in x excited state = -13.6/x² eV
The potential energy in x excited state = (-13.6 × 2)/x² eV
Given, the potential energy in excited state = -13.6/2 eV
∴ we have, -13.6/2 = (-13.6 × 2)/x²
x² = 4
x = √4 = 2
∴ x = 2 is the required value.
