Q. The maximum number of sublevels, orbitals and electrons in $N$-shell of an atom are respectively
A) 4, 12, 32
B) 4, 16, 30
C) 4, 16, 32
D) 4, 32, 64
Explanation
(c)
For ‘$N$’ shell
$\because$ The number of shell ($n$)=4
∴The number of sub-levels or sub-shell $(l)$=4
The number of orbitals $= n^{2} = 4^{2} = 16$
and the number of electrons$= 2n^{2} = 2 \times 4^{2} = 32$
