Non-typical transition elements belong to?
Correct answer: D. Both A and B
- A. 2B
- B. 3B
- C. 1B
- D. Both A and B
Explanation
Non-typical transition elements belong to groups 2B and 3B.Group 2B consists of the zinc group elements, which include zinc (Zn), cadmium (Cd), and mercury (Hg). These elements are considered non-typical transition elements because they do not exhibit typical transition metal properties, such as multiple oxidation states or the formation of colored compounds.Group 3B, also known as the scandium group, consists of scandium (Sc), yttrium (Y), and lutetium (Lu). These elements are also considered non-typical transition elements due to their electronic configurations and properties that differ from other transition metals.

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.
