Question

Which of the following configurations represents atoms of the elements having the highest second ionization energy

  1. (a) 1 s to the power of 2 end exponent 2 s to the power of 2 end exponent 2 p to the power of 4 end exponent  
  2. 1 s to the power of 2 end exponent 2 s to the power of 2 end exponent 2 p to the power of 6 end exponent  
  3. (c) 1 s to the power of 2 end exponent 2 s to the power of 2 end exponent 2 p to the power of 6 end exponent 3 s to the power of 1 end exponent  
  4. 1 s to the power of 2 end exponent 2 s to the power of 2 end exponent 2 p to the power of 6 end exponent 3 s to the power of 2 end exponent  

The correct answer is: (c) 1 s to the power of 2 end exponent 2 s to the power of 2 end exponent 2 p to the power of 6 end exponent 3 s to the power of 1 end exponent


    Because for removing second electron, it has to be taken out from stable configuration that needs a large amount of energy.
