Answer:

The seventh period of the periodic table contains elements with atomic numbers Z = 87–114. The element with Z = 114 is thus available in the seventh period.

In the seventh period, the first two elements are s-block elements, the next 14 are f-block elements (until Z = 89), the next 10 are d-block elements (Z = 89 to Z = 112), and the last two are p-block elements (Z = 113 to Z = 118). Thus, Z = 114 is the second p-block element in the seventh period of the periodic table.

So, Z = 114 is in the seventh period and fourth group of the periodic table.
