Which has a complex anion?
Correct answer: C. K2PtCl6
- A. Na3AlF6
- B. K2SiF6
- C. K2PtCl6
- D. All
Explanation
A complex anion is an anion that contains a metal atom surrounded by ligands. Na3AlF6 and K2SiF6 actually represent double salts since the presence of F- is detected as 3NaF.AlF3 and 2KF.SiF4. The true complex is K2PtCl6.

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.
