_ is used to measure atomic radii?
Correct answer: C. X-rays
- A. Gamma rays
- B. Alpha rays
- C. X-rays
- D. Beta rays
Explanation
Atomic radii are in the range of 10-1000pm. The wavelenght of X rays also lies within this range, thus via resonance, we can measure atomic radii using X-rays

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
