question_answer 1)

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

Answer:

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.
