MCQ
When is hydrogen stable?
- AWhen the electron jumps to higher energy levels.
- BWhen an electric field is introduced.
- CWhen a magnetic field is introduced.
- ✓When the electron is at its ground state.
✓
Answer
Correct option: D.
When the electron is at its ground state.
The hydrogen atom is stable when the electron rests at the ground level of energy, i.e. when the principal quantum number, $n = 1. '$
In other words, when the electron is revolving in the first orbit around the nucleus, the hydrogen atom is stable.
