Question

Which of the following has the electronic configuration open square brackets A r close square brackets 3 d to the power of 5 end exponent?

  1. Cr    
  2. F e to the power of 3 plus end exponent    
  3. M n    
  4. V    

The correct answer is: F e to the power of 3 plus end exponent


    F e open parentheses 26 close parentheses colon open square brackets A r close square brackets 3 d to the power of 6 end exponent 4 s to the power of 2 end exponent
    F e to the power of 3 plus end exponent colon left square bracket A r right square bracket 3 d to the power of 5 end exponent
