The pair of ions having same electronic configuration is.....

Answer»

`Cr^(3+) , Fe^(3+)`
`Fe^(3+), Mn^(2+)`
`Fe^(3+), Co^(3+)`
`SC^(3+), Cr^(3+)`

SOLUTION :`Cr^(3+) = [Ar]^(18) 3d^(3), Fe^(3+) = [Ar]^(18) 3d^(5), Mn^(2+) = [Ar]^(18) 3d^(5)`
THUS, `Fe^(3+) and Mn^(2+)` have the same ELECTRONIC CONFIGURATION
