Question

Among N‐³,O‐²,f‐,Na+,mg+² and Al‐³ a) What is common in then b) Arrange them in increasing ionic radii ​

Answer 1

Answer:

(a)they are isoelectronic species

they have same number of electrons.

(b) p/e ratio decides the size of ionic radii.

Higher is the p/e ratio, less is the ionic radii.

so increasing order will be

Al3+<Mg2+<Na+<Mg2+<O2- <N3-
