Question

N
3-
, O2-
, F-
, Na+
, Mg2+, and ,Al3+
Arrange them in the order of increasing ionic radii.
​

Answer 1

Answer:

The ionic radii of isoelectronic species increases with a decrease in the magnitudes of nuclear charge.

The arrangement of the given species in order of their increasing nuclear charge is as follows:

N3– < O2– < F– < Na+ < Mg2+ < Al3+

Nuclear charge = +7 +8 +9 +11 +12 +13

Therefore, the arrangement of the given species in order of their increasing ionic radii is as follows:

Al3+ < Mg2+ < Na+ < F– < O2– < N3–
