Question

Amongst the ions Na+, Mg2+, F and 02-,
which one has the largest ionic radius and
which one has the smallest ionic radius ?
Explain.​

Answer 1

Answer:

largest ionic radius is of O2-

and smallest ionic radius is of Mg2+

Explanation:

cation have smaller radius as compared to anion

increase in positive charge denotes increase in no. of protons which means the electrons are attracted more towards the centre making the atom smaller. so larger the positive charge smaller the size and larger the negative charge larger is the size
