Possible Quantum Numbers for Ground State Electron in an Atom with Atomic Number 19
The four sets of quantum numbers given are:
(a) n= 2, l= 0, m= 0
(b) n =2, l= 1, m=0
(c) n= 3, l= 1, m=-1
(d) n=3, l=2, m=2
Out of these four, only one set of quantum numbers is not possible for an electron in the ground state of an atom with atomic number 19. Let us examine each set of quantum numbers in detail.
(a) n= 2, l= 0, m= 0
This set of quantum numbers corresponds to the 1s orbital, which is the ground state orbital for hydrogen. However, for an atom with atomic number 19, the ground state electron will not occupy the 1s orbital but rather the 4s orbital.
(b) n =2, l= 1, m=0
This set of quantum numbers corresponds to the 2p orbital, which is possible for an atom with atomic number 19. However, the ground state electron will not occupy this orbital but rather the 4s orbital.
(c) n= 3, l= 1, m=-1
This set of quantum numbers corresponds to the 3p orbital, which is possible for an atom with atomic number 19. However, the ground state electron will not occupy this orbital but rather the 4s orbital.
(d) n=3, l=2, m=2
This set of quantum numbers corresponds to the 3d orbital, which is possible for an atom with atomic number 19. However, the ground state electron will not occupy this orbital but rather the 4s orbital.
Conclusion:
Therefore, the set of quantum numbers that is not possible for an electron in the ground state of an atom with atomic number 19 is (a) n= 2, l= 0, m= 0.

D. because in the ground state configuration d orbital, that is n=3 l=2 m=2 ,not involved since the ground state configuration is 1s2 2s2 2p6 3s2 3p6 4s1.
