MCQ
The number of completely filled shells for the element ${ }_{16} S ^{32}$ is
- A$1$
- ✓$2$
- C$3$
- D$4$
✓
Answer
Correct option: B.
$2$
b
(b)
(b)
Atomic number of ${ }_{16} S ^{32}$ is $16$ . Its electronic configuration using $2 n^2$ rule is
${ }_{16} S =\underbrace{1 s^2, 2 s^2 p^6}_{[ Ne ]}, \underbrace{3 s^2 p^4}_{\text {Unfilled }}$
So, number of fully filled orbits or shells is $2 .$
