In terms of period and group where would you locate the element

Question:

In terms of period and group where would you locate the element with =114?

Solution:

Elements with atomic numbers from $Z=87$ to $Z=114$ are present in the $7^{\text {th }}$ period of the periodic table. Thus, the element with $Z=114$ is present in the $7^{\text {th }}$ period of the periodic table.

In the $7^{\text {th }}$ period, first two elements with $Z=87$ and $Z=88$ are $s$-block elements, the next 14 elements excluding $Z=89$ i.e., those with $Z=90-103$ are $f-$ block elements, ten elements with $Z=89$ and $Z=104-112$ are $d$ - block elements, and the elements with $Z=113-118$ are $p-$ block elements. Therefore, the element with $Z=114$ is the second $p$-block element in the $7^{\text {th }}$ period. Thus, the element with $Z=114$ is present in the $7^{\text {th }}$ period and $14^{\text {th }}$ group of the periodic table.
