Five valence electrons of `""_(15)P` are labelled as

If the spin quantum of B and Z is `+1/2`, the group of electrons with three of the quantum number same are

Options

A. AB, XYZ, BY
B. AB
C. XYZ, AZ
D. AB, XYZ

Answer

B, D

Explanation

`""_(15)P=1s^(2),2s^(2)2p^(6),3s^(2)3p^(3)`

`BrArrn=3,l=0,m=0,s=+1/2`
`ArArrn=3,l=0,m=0,s=-1/2`
`XrArrn=3,l=1,m=-1,s=+1/2`
`YrArrn=3,l=1,m=+1,s=+1/2`
`ZrArrn=3,l=1,m=0,s=+1/2`
So group of electrons with three of the quantum numbers are same
AB (n, l and m)
`XYZ(n,l,s)`
BZ(n, m, s) [m = 0 for `P_(z)` orbital]
AB and AB, XYZ.
