Ce58 is a member of__________?
Correct answer: D. f-block
- A. S-block
- B. P-block
- C. d-block
- D. f-block
Explanation
Cerium, Ce, atomic number 58, is a lanthanide, and lanthanides belong to the f-block because the 4f subshell is being filled across the series. The likely mistake is choosing d-block because cerium is a metal, but block classification depends on the subshell receiving the differentiating electron.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
