JEE Main 2022 — Structure Of Atom Question with Solution
From: JEE Main 2022 (Online) 27th July Evening Shift
Question
Outermost electronic configurations of four elements A, B, C, D are given below :
(A)
(B)
(C)
(D)
The correct order of first ionization enthalpy for them is :
Choose an option
Show full solutionCorrect option: B
Correct answer
B(B) < (A) < (D) < (C)
Step-by-step explanation
Orbitals with fully filled and half-filled electronic configuration are stable, and require more energy for ionization
Elements with greater electronegativity require more energy for ionisation
Hence the correct order is
Elements with greater electronegativity require more energy for ionisation
Hence the correct order is
