    ok in anion the greater will be the charge more will be the radius because when we add an electron no. of proton decreases as compare to electron which means nucleous effective charge decreaes as a rseult size increaes in anion more the positive charge less the radius as proton no. increses because of lose of an electron means more nuclear charge which attracts the electron present aND bring closer as a result bond length decreases

    conclusion: in anion more charge greater radius in cation more charge smaller radius

    as u know down the group bond length increaes and if there is charge also same then we will use normal trend b)Mg2+ < Ca2+ <Ba2+ c)f- < Cl- < Br- d) Cu 2+< Zn 2+ <Ba 2+ (as u know in period bond length decrease e)O2- <P3- < Si 4- ( in isolelectronic species we will also consider the same method acc. to charge)
