Answer
Elements whose atomic number is from $Z=87$ to $Z=114$ are available in the seventh period of periodic table. Therefore, the element having $Z=114$ is available in the seventh period in periodic table.
In the seventh period, initial 2 elements with $Z=87$ and $Z=88$ are the elements of s-block and the following 14 elements except $Z=89$ i.e., those from $Z=90$ to $Z=103$ are elements of $f$ - block, and next 10 elements from $Z=$ 89 and $Z=104$ to $Z=112$ are elements of d-block, next the elements from $Z=113$ to $Z=118$ are elements of $p$ block. In this manner, the element $Z=114$ is the $2^{\text {nd }}$ element of $p$-block in the seventh period of the periodic table.
Therefore, the element $Z=114$ is available in the seventh period and fourth group in the periodic table.
