The total number of inner transition elements in the periodic table is:
Correct answer: C. 28
- A. 10
- B. 14
- C. 28
- D. 30
Explanation
This is the correct option because inner transition elements are those elements that have their outermost electrons in the f orbitals. These elements are typically placed separately at the bottom of the periodic table. There are 14 elements in the f-block, specifically the lanthanides (from cerium to lutetium) and the actinides (from thorium to lawrencium), which make a total of 28 inner transition elements.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
