Which one can form more acidic oxide?
Correct answer: B. Mn
- A. Sc
- B. Mn
- C. V
- D. Ti
Explanation
The acidic strength of oxides of different elements will depend on the tendency of oxygen atoms to accept electrons. When the oxygen atom is attached to some electronegative element its acidic character increases as the electronegative element pulls the electrons towards its side. In the periodic table, the electropositive character decreases from right to left across a period and increases down the group. Since Mn appears after Sc, V, and Ti in the periodic table it is comparatively more electronegative, and hence Mn is the most acidic oxide among these 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.
