In which one of the following pairs of experimental observations and phenomenon does the experimental observation correctly account for phenomenon:
(1) X-ray spectra Charge on the nucleus
(2)α -particle scattering Quantized electron orbit
(3)Emission spectra The quantization of energy
(4)The photoelectric effect The nuclear atom
Ans: (c)Emission spectra The quantization of energy
