Question

How many electrons in an atom with atomic number 105 can have open parentheses n plus l close parentheses equals 8 ?

  1. 30    
  2. 17    
  3. 15    
  4. Unpredictable    

The correct answer is: 17


    5 f to the power of 14 end exponent comma blank 6 d to the power of 3 end exponent rightwards double arrow 17 e to the power of minus end exponent
    5 f to the power of 14 end exponent equals open parentheses n plus l close parentheses equals 5 plus 3 equals 8
    6 d to the power of 3 end exponent equals open parentheses n plus l close parentheses equals 6 plus 2 equals 8
