Consider theisoelectronicspeciesNa^(+) , Mg^(2+) F^(-) and O^(2-). Thecorrectorderofincreasinglengthof theirradii is ……….

Answer»

`F^(-) lt O^(2-) lt MG^(2+) lt Na^(+)`
`Mg^(2+)lt Na^(+) lt F^(-)lt O^(2-)`
`O^(2-) lt F^(-) lt Na^(+)lt Mg^(2+)`
`O^(2-) lt F^(-) lt Mg^(2+)lt Na^(+)`

Solution :Amongstisoelectronicspeciesionic RADII increaseas the + vechargedecreases or thenegativechargeincreases. Thus theionic radiiincreasein the ORDER`:Mg^(2+) lt Na^(+) lt F^(-)O^(2-)` i.e., option( b) iscorrect .
