alleryThe maximum number of electrons in the subshell with $n = 4, l = 2$ is
A$10$
B$2$
C$6$
D$14$
Answer & Solution
Correct answer: A. $10$
$l = 2$ is a d subshell — it has $2l+1 = 5$ orbitals, each holding 2 electrons → 10 max.
The d-block of the periodic table has 10 elements per row for exactly this reason.
