What may be stable oxidation state of the transition element with the following d electronconfiguration in the ground state of their atoms ? 3d^(3) , 3d^(5), 3d^(8)and 3d^(4) |

Answer» Solution :`3d^(3) 4s^(2) = + 5 , 3d^(5) 4s^(1) = + 6 , 3d^(5)4s^(2) = +2 , + 7 , 3d^(8)4s^(2) = + 2 , 3d^(4)4s^*(2) = 3d^(5)4s^(1) = + 6 ( & + 3)` Note. The MAXIMUM oxidation states of reasonable stability CORRESPOND to the sum of s and d- electrons upton Mn. After that, there is abrupt decrease in the stability of higher oxidation states. |
