According to which one of following law the density of atom is uniform ?
Correct answer: A. J.J.Thomson model
- A. J.J.Thomson model
- B. Rutherfords model
- C. Bohrs model
- D. All of the above laws contradict the statement
Explanation
In Thomson's model, the atom was considered a diffuse sphere of positive charge with electrons embedded in it, so its positive charge and mass were treated as spread uniformly. Rutherford's model concentrated most mass and positive charge in a small nucleus, while Bohr's model also used a central nucleus. Students may choose d because the wording says 'law', but Thomson's model is the intended answer.

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.
