Question

On an X-ray diffraction photograph, the intensity of the spots depends on

• A. neutron density of the atoms/ions
• B. electron density of the atoms/ions
• C. proton density of the atoms/ions
• D. photon density of the atoms/ions

Hint:

X-ray diffraction is sensitive to electron density, making it useful for analyzing atomic structures.

Answer 1

The Correct Option is B

Step 1: Diffraction and electron density.
The intensity of spots in X-ray diffraction depends on the electron density of the atoms/ions since X-rays interact with the electron cloud.

Step 2: Conclusion.
Thus, the correct answer is option (B).

Final Answer: \[ \boxed{\text{(B) electron density of the atoms/ions}} \]
