Passage / Comprehension
Consider a set of atoms where highest possible filled shell number for any atom can be maximum 5 and for the electrons of penultimate electron highest m = +1 then :
The element can not be among the set is :
Options:
Answer:
C
Solution:
The condition says the highest filled shell n ≤ 5 and for penultimate electrons m(max) = +1, which restricts allowed orbital filling (mainly up to 5p/5d patterns).
Among the given elements, Cs has electronic configuration ending in 6s¹, meaning its highest shell is n = 6.
This violates the condition of maximum shell number 5.
Therefore, Cs cannot be part of the given set, while the others fit within the limit.
