Question

Which of the following orders of ionic radii is correctly represented?

Answer 1

Answer:

option kaha hai bhai ...........

Answer 2

Answer:

The cations lose the electrons and generally are smaller than parent atom in size. On the other hand, the anions can add the electrons and can be larger than parent atom in size. Therefore the order must be H^{-}>H>H^{+} (Option A). For the isoelectronic species, an ionic radius generally decreases with the increase in the atomic number, (nuclear charge). The correct order is following- O^{2-}>F^{-}>Na^{-} and N^{3-}>Mg^{2+}>Al^{3+}.
