Q. Maximum number of electrons in a subshell of an atom is determined by the following:
A) 2l + 1
B) 4l − 2
C) 2n²
D) 4l + 2
Explanation
[Solution from source] A subshell with quantum number l has (2l + 1) orbitals, each holding 2 electrons, so the maximum is 2(2l + 1) = 4l + 2. 2l + 1 counts orbitals, not electrons, and 2n² is for a whole shell. Answer (4).
