Explain briefly how +2 state becomes more and more stable in the first half of the first row transition elements with increasing atomic number?

Compare the stability of +2 oxidation state for the elements of the first transition series .

Explain the following observation : Among the divalent cations in the first series of transition elements, manganese exhibits the maximum paramagnetism .

Explain the following observation : In general, the atomic radii of transition elements decrease with atomic number in a given series.

how ionic radius of elements of first transition series change in the period?

Average life time is more/less than half life time for a first order reaction.

To what extent do the electronic configurations decide the stability of oxidation states in the first series of the transition elements? Illustrate your answer with examples.

Describe the trends in the elements of group 16 in order of increasing atomic number: Oxidation state.

The E_(M^(2+) // M)^@ for copper is positive (0.34 V). Copper is the only metal in the first series of transition elements showing this behaviour.

The halides of transition elements become more covalent with increasing oxidation state of metal. Why ?

Lanthanoids are much more paramagnetic than transition elements. Explain.
