Which of the following has largest lonic size?
Correct answer: C. N3-
- A. F-
- B. O2-
- C. N3-
- D. Na+
Explanation
Ionic size decreases along the period form left to right. More over anions are of larger size as compare to cations. So, order of ionic radius is N-3>O-2> F-1> Na+1

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.
