Question

A neutral atom will have the lowest ionization potential when its electronic configuration is

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

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


    Ionization potential is least for alkali metals and it decreases down the group
