Which has maximum `EAN` of the underbold atoms?
`(Cr=24,Co=27,Fe=26,Ni=28)` .

The complex ion which has no ""d"" electrons in the central atom is (at. Cr=24, Mn=25, Fe=26,Co=27)

For the four successive transition elements (Cr, Mn, Fe, and Co), the stability of +2 oxidation state will be there in which of the following order ? (At. Nos. Cr = 24, Mn = 25, Fe = 26, Co = 27)

For the four successive transition elements (Cr, Mn, Fe, and Co), the stability of +2 oxidation state will be there in which of the following order ? (At. Nos. Cr = 24, Mn = 25, Fe = 26, Co = 27)

The metal ion in complex underline(A ) has EAN identical to the atomic number of krypton . underline (A) is ( Atomic no. Of Cr =24,Fe=26 ,pd =46)

The geometry ion which hs no d electrons in the central metal atom is : [Atomic number Cr=24, Mn=25, Fe=26, Co=27 ]
