A set of atoms in an excited state decays:
Correct answer: A. In any general state with lower energy
- A. In any general state with lower energy
- B. In any state when excited by electric field
- C. In any state when excited by magnetic field
- D. None of these options are correct
Explanation
As we know, atoms are stable in the ground state, when they move to another level by gaining energy, they get excited and are ready to lose energy to get back to the ground state. This shows, generally excited state atoms decay to any of the states with lower energy.Hence,the correct option is A in any general state with lower energy which is more stable than the excited state.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
