Short Answer TypeIn terms of period and group were would you locate the element with Z = 114?
We know that the gaps of atomic numbers in a group are 8, 8, 18, 18, 32. Hence the element which proceeds the element with Z = 114 in the same group must have an atomic number equal to 114 - 32 = 82. This represents lead (Pb) which is present in the 6th period and belongs to group 14 of the p-block. This means the element with Z = 114 must also belong to group 14 (second p-block element) of 7th period. Thus the location of the element with Z = 114 in the periodic table is:
period = 7th, Block = p-Block, Group = 14.
