Question

Which species has the maximum ionic radius?
Na+
02-
F-
Mg2+​

Answer 1

Answer:

hey

Explanation:

answer :- Option B

• greater the negative charge more will be the radius.

Answer 2

Answer:

The correct option is O2-

Explanation:

F− and O2−are isoelectronic species possessing 10 electrons each.

Li+and B +

are isoelectronic species possessing 2 electrons each.

Since in the case of O2−

, there is greater electron-electron repulsion and lesser effective nuclear charge, O2−

has the largest ionic radius in this case.
