Statements that are true of transition and inner transition metals are : This question has multiple correct options

  • A. osmium is the heaviest transition metal
  • B. \( C u^{+}\left(3 d^{10}\right) \) is more stable than \( C u^{2+}\left(3 d^{9}\right) \) in aqueous medium
  • C. actinides are generally strong reducing agents
  • D. \( Y, L a \) and \( A c \) exhibit variable valency

Step-by-step solution

Actinides exhibit multiple oxidation states and low reduction potentials, making them strong reducing agents. Option A is false because osmium (atomic number 76) is not the heaviest transition metal; heavier ones like mercury (80) exist. Option B is false because Cu²⁺ is more stable than Cu⁺ in aqueous solution. Option D is false because Y, La, and Ac typically show only +3 oxidation state, not variable valency.
