Which of the following is not permissible arrangement of electrons in an atom ?

• A

  $\mathrm{n}=3, l=2, \mathrm{~m}=-3, \mathrm{~s}=-\frac{1}{2}$
• B

  $\mathrm{n}=4, l=0, \mathrm{~m}=0, \mathrm{~s}=-\frac{1}{2}$
• C

  $\mathrm{n}=5, l=3, \mathrm{~m}=0, \mathrm{~s}=+\frac{1}{2}$
• Correct answer
  D

  $\mathrm{n}=3, l=2, \mathrm{~m}=-3, \mathrm{~s}=-\frac{1}{2}$

Hence, the correct answer is option: 'D'.
