Which ofthe followingelementshas mostpositiveelectrongainenthalpy ?Fluorinenitrogen neon. |
|
Answer» SOLUTION :Bothnitrogenand neonhave positive electrongainenthalpies. Butneonhas muchhigherpositiveelectron gain enthalpy because of itsmuch morestable INERTGAS CONFIGURATION than the lessstableexactlyhalf-filledelectronicconfigurationof nitrogen. Alternatively in NEON , the newelectronhas to beplacedin a muchhigherenergy 3S- orbital of the newshellwhilein case of N , thenewelectronis toplacedin the 2p-orbital of the sameshell. |
