atd01: Hmm.. I did that too

atd01: The electronic configurations of Zn, Cd and Hg are represented by the general formula (n-1)d10 ns2. The orbitals in these elements are completely filled in the ground state as well as in their common oxidation states. Therefore, they are notregarded as transition elements.

devanshsahu700: can you tell the reason for b

atd01: Fe+3 is more stable than Fe+2 due to half-filled subshell configuration of Fe+3 ( ie. 3s2 3p6 3d5 is more stable when compared to 3s2 3p6 3d6 )

atd01: Moral of the story is : Learn to use Google
