Q.
The element with atomic number $114$ belongs to
Classification of Elements and Periodicity in Properties
Solution:
The outermost electronic configuration of element
$(_{114}Z)$ is $[Rn] 5 f^{14}6d^{10} 7s^2 7p^2$
It has $n = 7$ so period $7$
It belongs to $p$-block, so group number
$=10 + 4 = 14$
i.e., group $14$ and period $7$.
