Question

The correct arrangement of O, P and N in order
of increasing radii is
O< <P
2) P<O<N
3) O <P<N
4) N<O<P​

Answer 1

Answer: it should be O<N<P

Explanation:

We know that higher the no.of shells more will be the radius...hence P is the largest among these.

Now,in the same period as the no.of electron increases ,radius shrinks due to inter atomic attraction..so O<N

Hence,O<N<P
