Answer 2

3 is not a possible value of azimuthal quantum number for an electron with n=3.

• n is called the principal quantum number.
• l is called azimuthal quantum number. The orbital of l equal to 0 is "s", for l equal to 1 is " p", for l equal to 2 is "d" and for l is equal to 3 is "f".
• For l=0 the orbital is 3s which is possible.
• For l=1 the orbital is 3p which is possible.
• For l=2 the orbital is 3d which is possible.
• For l=3 the orbital is 3f which is not possible.
• Hence the correct option is d.
