Elements/ions having same number of electrons are known as isoelectronic species. Arrange the following elements incorrect order of atomic/ionic radii and choose the correct from the four choices given below `O^(2-), Na^(+), Mg^(2+), F^(-), Al^(3+)`A. `Al^(3+)lt Mg^(2+)lt Na^(+) lt F^(-)lt O^(2-)`B. `Al^(3+)lt Na^(+)lt Mg^(2+)lt F^(-)lt O^(2-)`C. `Al^(3+)gt Mg^(2+)gt Na^(+)gt O^(2-)`D. None of the above |
