Question

Maximum number of electrons that can be accommodated in the subshell with azimuthal quantum number $l=4$ , is:

• A. $10$
• B. $8$
• C. $16$
• D. $18$

Answer 1

Answer: (D)

Value of $l\Rightarrow 0$ to $n-1$
and
$l=0=s=1$ orbitall
$=1=p=3$ orbitall
$=2=d=5$ orbitall
$=3=f=7$ orbitall
$=4=g=9$ orbital
So, electrons in $l=4$ are $18e^{-1}$
