Henry Moseley studied characteristic X -ray spectra of elements. The graph which represents his observation correctly is Given v = Frequency of X-ray emitted Z = Atomic number

Correct answer

2

Step-by-step solution

Moseley's observation on characteristic X -ray spectra of elements relates frequency ( v ) of X -rays emitted to the atomic number by the following relation: v = a ( Z - b ) The plot of v vs Z is linear. Based on this observation, the periodic law defined as the physical and chemical properties of the elements are periodic functions of their atomic numbers.
