Question

Which one of the following elements has the highest ionisation energy

  1. left square bracket N e right square bracket 3 s to the power of 2 end exponent 3 p to the power of 1 end exponent  
  2. left square bracket N e right square bracket 3 s to the power of 2 end exponent 3 p to the power of 2 end exponent  
  3. left square bracket N e right square bracket 3 s to the power of 2 end exponent 3 p to the power of 3 end exponent  
  4. left square bracket A r right square bracket 3 d to the power of 10 end exponent 4 s to the power of 2 end exponent 4 p to the power of 2 end exponent  

The correct answer is: left square bracket N e right square bracket 3 s to the power of 2 end exponent 3 p to the power of 3 end exponent


    Since e to the power of minus end exponent is to be removed from exactly half filled p-orbital.
