Question

Arrange the following in the increasing order of ionic radius. N^3 - , Na^+, F^-, O^2 - , Mg^2 +

(P.S - I am need a good explanation)​

Answer 1

Answer:

These are isoelectronic species.species having same no.of electrons are called isoelectronic species.

Explanation:

p/e ratio decides the ionic radius.

Higher is the p/e ratio , smaller is the size of ionic radius.

So, the increasing order of ionic radius is

N^3-> O^2->F^1->Na^+>Mg^2+

Answer 2

Answer:

ionic redius

Explanation:

ionic redius of N>O>F>Mg>Na

nagetive ions have greater ionic redius then positive ions.. ......i hope this will help U
