• question_answer 15) In terms of period and group where would you locate the element with Z = 114?

The last member of the sixth period is the element radon with atomic number 86. Therefore, the element with atomic number 114 belongs to 7th period. In 7th period $7s,5f,6d$ and op-orbitals are filled. $7s,\text{ }5f$and $6d$-orbitals filling correspond to 26 elements, i.e., the end member will be with atomic number 112. It means the element in question is a second $6p$-element, i.e., it belongs to group (10 + 4) = 14.
