Why do 5f electrons take part in bonding more than 4f electrons?
A5f lies far below 4f
B5f has no angular part
C5f is less buried than 4f
D5f is more buried than 4f
Answer & Solution
Correct answer: C. 5f is less buried than 4f
The 5f orbitals extend further out than the deeply buried 4f orbitals, so they can join in bonding.
