Explanation:
Before I tell u the answer I must tell you how to learn it for s block
- more the positive charge on atom less is the size
- more is the negative charge more is the size
(both valid for comparing ions of same period)
so this rule is just comman sense but my teacher told me while I was preparing for jee(I wasn't mad I noticed it too)
may be explained by fazan's rule(not sure)
what so ever the answer according to above mentioned rule is
mg+2 < Na+1 < O-2 < N-3
hope it Is helpful
Remember for jee/neet etc NCERT is must to read thanks to meet I qualified both main and advance with good rank
