If the ionic radii of each K^(+) and F^(-) are 1.34Å , then tha atomic radii of K and F will be respectively:

If the ionic radii of K^(+) and F^(-) are nearly the same (i.e., 1.34A^(o) ) ,then the atomic radii of K and F respectively are:

The properties of the elements (atomic/ionic radii, electron gain enthalpy, ionization enthalpy, electronegativity, valence, oxidising/reducing power, acid/base character, etc.) which are directly or indirectly related to their electronic configirations are called periodic properties. These properties show a regular gradation on moving from left to right in a period or form top to bottom in a group. Down a group, the atomic/ionic radii, metallic character and reducing character increase while ionization enthalpy and electronegativity decrease. Along a period from left to right, atomic/ionic and metallic character decrease while ionization enthaloy, electronegativity, non-metallic character and oxiding power increase. However, electron gain enthalpy becomes less negative down a group butmore negative along a period. In contrast, inert gases have positive electron gain enthalpies which do not show may regular trend. If the ionic radii of K^(+) and F^(-) are about 1.34 Å each, then the expected value of atomic radii of K and F should be respectively:

The ionic radii of F^(-) and O^(2-) respectively are 1.33 Å and 1.4 Å, while the covalent radius of N is 0.74 Å. The correct statement for the ionic radius of N^(3-) from the following is :

The ions O^(2-), F^(-), Na^(+), Mg^(2+) , and A1^(3+) are isolectronic. Their ionic radii show
