JEE Advanced levelSingle correct optionDifficulty 3 of 3as156
The orbital of an electron has 3 radial nodes and orbital angular momentum 20ℏ. The maximum number of electrons that can be accommodated in the corresponding subshell is
A22
B14
C18
D10
Answer: C
l(l+1)=20 gives l=4. The subshell has 2l+1=9 orbitals, holding 18 electrons. (Here n=3+4+1=8.)
