Question

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

Answer 1

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

In the $7^{ th}$ 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 $7^{ th}$ period.
Thus, the element with $Z$ = $114$ is present in the $7 ^{th}$ period and $14^{ th}$ group of the periodic table.
