Question

The ionic radii ( mathringA ) of C4- and O2- respectively are 2.60 and 1.40. The ionic radius of the isoelectronic ion N3- would be (A) 2.6 (B) 1.71 (C) 1.4 (D) 0.95

Tardigrade Admin · Accepted Answer

C4-,N3- and O2- are isoelectronic species. The ionic radius of isoelectronic species decreases with increase the nuclear charge. Hence, the order of ionic radius is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/5bb512e06724720b00abf9a74454a1e6-.png" />
