Most Important Selected Qs for JEE AdvancedChemistryClassification of Elements and Periodicity in Properties
In which one of following processes, the involved energy change is different from remaining three?
Options
- ANa ( g )+ e ⁻ Na ⁻( g )
- BMg ( g )+ e ⁻ Mg ⁻( g )
- CN ( g )+ e ⁻ N -( g )
- DO ⁻( g )+ e ⁻ O ²⁻( g )
Correct answer
A. Na ( g )+ e ⁻ Na ⁻( g )
Step-by-step solution
array ll Na ( g )+ e ⁻ Na ⁻( g ) & EGE =- ve Mg ( g )+ e ⁻ Mg ⁻( g ) & EGE =+ ve N ( g )+ e ⁻ N ⁻( g ) & EGE =+ ve O ⁻( g )+ e ⁻ O ²⁻( g ) & 2^ nd EGE is always + ve array
