Question

Which of the following electronic configurations in the outermost shell is characteristic of alkali metals

  1. (a) left parenthesis n minus 1 right parenthesis s to the power of 2 end exponent p to the power of 6 end exponent comma n s to the power of 2 end exponent p to the power of 1 end exponent   
  2. left parenthesis n minus 1 right parenthesis s to the power of 2 end exponent p to the power of 6 end exponent d to the power of 10 end exponent comma n s to the power of 1 end exponent  
  3. (c) left parenthesis n minus 1 right parenthesis s to the power of 2 end exponent p to the power of 6 end exponent comma n s to the power of 1 end exponent   
  4. n s to the power of 2 end exponent p to the power of 6 end exponent d to the power of 1 end exponent  

The correct answer is: (c) left parenthesis n minus 1 right parenthesis s to the power of 2 end exponent p to the power of 6 end exponent comma n s to the power of 1 end exponent


    Alkali metals have the configuration
