Chemistry · Classification of Elements and Periodicity in Properties
हिन्दीHenry Moseley observed regularities in the characteristic X-ray spectra of elements. A plot of \( \sqrt{\nu} \) (where \( \nu \) is frequency) against which parameter gave a straight line?
Correct answer · Option 2
Atomic number (\( Z \))
Explanation
Moseley showed that the plot of \( \sqrt{\nu} \) vs atomic number (\( Z \)) gives a straight line, proving that atomic number is a more fundamental property than atomic mass.
