Question

The ionic raddi of F- and Na+ are 133 and 98 pm respectively​

Answer 1

Explanation:

The ionic radius of fluoride ion is bigger then that its parent atom.

This is because when fluorine atom gains an electron number of electrons becomes more than the number of protons due to which effective nuclear charge on valence electrons decreases and resulting in increase in size of an ion.

The ionic radius of sodium ions is smaller then that its parent atom.

This is because when sodium atom looses an electron number of electrons becomes less than the number of protons due to which effective nuclear charge on valence electrons increases and resulting in shrinking in size of sodium ion.

By this ionic radius reduces to 98 pm which even smaller than that of the fluoride ion's ionic radius 133 pm.
