The Na atom cannot produce X-rays because _.
Correct answer: B. Inner shell transition is not possible
- A. Inner shell transition is possible
- B. Inner shell transition is not possible
- C. It is non-radioactive
- D. None of these
Explanation
Correct Option: BThis option is correct because x-rays are produced by inner shell transition which is not possible in Na. From the electronic configuration, we can see that there are 2 electrons in the K shell,8 electrons in the L. shell and 1 electron in the M shell. Thus the inner shells are fully filled which doesn't allow the transition of electrons as a result the x-rays are not produced.

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.
