JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
The electronic configuration with the highest ionization enthalpy is
- A \([Ne]\, 3s^2\,3p^1\)
- B \([Ne]\, 3s^2\,3p^2\)
- C \([Ne]\, 3s^2\,3p^3\)
- D \([Ar]\, 3d^{10}\,4s^2\,4p^3\)
Answer & Solution
Correct Answer
(C) \([Ne]\, 3s^2\,3p^3\)
Step-by-step Solution
Detailed explanation
The smaller the atomic size, larger is the value of \(IP\). Further the atoms having half filled or fully filled orbitals are comparatively more stable, hence more energy required to remove the electron from such atoms.
