Question
Assign the position of elements having outer electronic configuration:
i. $n s^2 n p^4$ for $n=3$
ii. $(n-1) d^2 n s^2$ for $n=4$
✓

Answer

i. $n s^2 n p^4$ for $n=3$

Since $n=3$; the element belongs to the third period. Futher, the element belongs to the $p$-block and group number 16.
ii. $(n-1) d^2 n s^2$ for $n=4$, the element belongs to period number 4 and group number 4 .
