AIPMT PRELIMS 2011 Chemistry Electron Configuration MCQ Question
Type: MCQ-conceptual-Medium-Class 11
If n = 6, the correct sequence of filling of electrons will be
A
ns → np(n−1)d → (n−2)f
B
ns → n(n−2)f → (n−1)d → np
C
ns → (n−1)d → (n−2)f → np
D
ns → (n−2)f → np → (n−1)d
Correct Answer
Option B
Detailed Explanation
For n = 6, the filling order is determined by the (n+l) rule, where electrons fill the lowest energy orbitals first.
