NEETChemistryClassification of Elements and Periodicity in Properties
Why does nitrogen have positive electron gain enthalpy whereas oxygen has negative? However, oxygen has lower ionisation enthalpy than nitrogen. Explain.
Options
- ANitrogen's stable half-filled p-orbital (2p³) resists the addition of extra electrons, resulting in positive e
- BOxygen, with a 2p³ configuration, achieves stability by removing one electron, leading to a negative electron
- CNitrogen's higher ionisation enthalpy makes it less favourable to lose electrons compared to oxygen.
- DOxygen's smaller atomic size allows for easier removal of electrons, resulting in a negative electron gain ent
Correct answer
A. Nitrogen's stable half-filled p-orbital (2p³) resists the addition of extra electrons, resulting in positive e
Step-by-step solution
Correct Option is : (A) Nitrogen's stable half-filled p-orbital (2p³) resists the addition of extra electrons, resulting in positive electron gain enthalpy.
