JEE Main & Advanced Chemistry Structure of Atom Question Bank Quantum number, Electronic configuration and Shape of orbitals

  • question_answer Five valence electrons of \[{{p}^{15}}\] are labelled as If the spin quantum of \[B\] and \[Z\] is \[+\frac{1}{2}\], the group of electrons with three of the quantum number same are [JIPMER 1997]

    A)                 \[AB,\,XYZ,\,BY\]            

    B)                 \[AB\]

    C)                 \[XYZ,\,AZ\]      

    D)                 \[AB,\,XYZ\]

    Correct Answer: B

    Solution :

     For both A & B electrons \[s=-1/2\] & \[+1/2\] respectively, \[n=3,\,l=0,\,m=0\]
