Give reasons: Zn has highest value for `E^@(M^3+/M^2+) among 3d series elements.

Give reasons: i) Cu^(+2) (aq) is more stable than Cu^(+) ii) Ionisation enthalpy increases along transition elements from left to right iii) Zn has highest value for E^(@)(M^(3+)//M^(2+)) among 3d series elements

Give reason: Mn exhibits the higher oxidatoin state of +7 among 3d series transition elements.

Give reasons: i) Generally there is increase in density along 3d series of transition metals.

Assign reasons for each of the following: (i) Transition metals generally form coloured compounds. (ii) Manganese exhibits the highest oxidation state of +7 among the 3d-series of transition elements.

How many elements are there in 3d-series elements ?

Which is not correct about the chemistry of 3d and 4f series elements ?

Which M-M bond has highest bond energy?

Name the electrode system which have positive E^(0) value in 3d series. Give reason.

State reasons for the following: (i) Cu(I) ion is not stable in an aqueous solution. (ii) Unlike Cr^(3+)Mn^(2+), Fe^(3+) and the subsequent other M2+ ions of the 3d series of elements, the 4d and the 5d series metals generally do not form stable cationic species.
