For Na^(+), Mg^(2+),F^(-) and O^(2-) , thecorrectorder ofincreasingion

1.	For Na^(+), Mg^(2+),F^(-) and O^(2-) , thecorrectorder ofincreasingionicradii is
Answer» `MG^(2+) lt Na^(+)lt F^(-)lt O^(2-)` `O^(2-)lt F^(-)lt Na^(+) lg Mg^(2+)` `Na^(+)lt Mg^(2+)lt F^(-)lt O^(2-)` `Mg^(2+)lt O^(2-)lt Na^(+) lt F^(-)` Solution :Allth SPEICES have10 elementseach andhenceare isoelectronicions . Amongisoelectronicions , ionicsizeincreasesas the + Vechargedecrease orthe - ve chargeincreases i.e.,OPTION( a) is CORRECT .
