Question

Henry Moseley plotted a graph between $\sqrt{v}$ and $Z$, where $v$ was the frequency of $X$-ray emitted by an atom and $Z$ was its atomic number. This graph showed that

• A. the atomic mass is fundamental properties of an element
• B. the atomic number is fundamental property of an element
• C. Both (a) and (b)
• D. The frequency $(v)$ was independent of atomic number

Answer 1

Answer: (B)

Henry Moseley ploted a graph of $\sqrt{v}$ vs $Z$ and showed that the atomic number is more fundamental property of an element than its atomic mass.
