Question

In Moseley's experiment, the frequency of emitted X-rays ($ u$) is related to the atomic number ($Z$) of the target metal. Which of the following plots yields a straight line demonstrating this periodic law?

Prashant Kotian · Accepted Answer

Correct answer: B. Moseley bombarded high-speed electrons on different metal surfaces and obtained X-rays. He formulated the relationship , where and are constants. Thus, a plot of against yields a straight line, proving that atomic number, not atomic weight, is the fundamental property of an element.
