Question

Ionic radii are

  1. Inversely proportional to effective nuclear charge    
  2. Inversely proportional to square of effective nuclear charge    
  3. Directly proportional to effective nuclear charge    
  4. Directly proportional to square of effective nuclear charge    

The correct answer is: Inversely proportional to effective nuclear charge


    r subscript n end subscript equals fraction numerator n to the power of 2 end exponent a subscript 0 end subscript over denominator Z subscript e f f e c t i v e end subscript end fraction
    Thus, r subscript n end subscript proportional to fraction numerator 1 over denominator Z subscript e f f e c t i v e end subscript end fraction
