Question

A l to the power of 3 plus end exponent has a lower ionic radius than M g to the power of 2 plus end exponent because

  1. (a) M g atom has less number of neutrons than A l  
  2. A l to the power of 3 plus end exponent has a higher nuclear charge than M g to the power of 2 plus end exponent  
  3. (c) Their electronegativities are different  
  4. A l has a lower ionisation potential than M g atom  

The correct answer is: A l to the power of 3 plus end exponent has a higher nuclear charge than M g to the power of 2 plus end exponent
