Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Which of the following statements are correct for an electron that has n = 4 and\[m=-2\]? (1) The electron may be in a d-orbital (2) The electron is in the fourth principal electronic shell (3) The electron may be in a p-orbital (4) The electron must have the spin quantum number \[=+\frac{1}{2}\]A) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: B
Solution :
If\[n=4\]then\[l\]can be 2. Hence, the electron may be in a d-orbital. As\[n=4,\]the electrons is in the fourth principal electronic shell.
