Ionic radius (in Ã… ) of As ³⁺, Sb ³⁺ and Bi ³⁺ follow the order

Options

  1. AAs ³⁺> Sb ³⁺> Bi ³⁺
  2. BSb ³⁺> Bi ³⁺> As ³⁺
  3. CBi ³⁺> As ³⁺> Sb ³⁺
  4. DBi ³⁺> Sb ³⁺> As ³⁺

Correct answer

D. Bi ³⁺> Sb ³⁺> As ³⁺

Step-by-step solution

Ionic radius increases in a group from top to bottom i.e., it increases from As ³⁺ to Bi ³⁺ .
