The valency of an atom will be one if there is a sufficient gap between first and second:
Correct answer: B. Ionization energy
- A. Electron affinity
- B. Ionization energy
- C. Electronegativity
- D. None of these options is correct
Explanation
A sufficient gap between the 1st and 2nd ionization energy indicates that the valency is 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.
