With reference to the first row transition metals.
Name a metal which shows maximum number of oxidation states.

With reference to the first row transition series: i) Name the metal which possesses maximum number of oxidation states. ii) Among Zn^(+2) and Cu^(+2) which is colourless? iii) Between Ti^(2+) and V^(2+) which ion contains more number of unpaired electrons?

What are transition metals ?

Name the metal of the 1^(st) row transition series that Exhibits maximum number of oxidation states.

(i) Name the element of 3d-transition series which shows maximum number of oxidation states. Why does it show so? (ii) Which transition metal of 3d-series has positive E^0(M^(2+)//M) value and why? (iii) Out of Cr^(3+) and Mn^(3+) which is a stronger oxidizing agent and hy? (iv) Name a member of the lanthanoid series which is well known to exhibit + 2 oxidation state. (v) Complete the following equaton: MnO_(4)^(-) + 8H^(+) + 5e^(-) to

With reference to first row transition series. Between Ti^(+2) and V^(+2) which ion contains more number unpaired electrons.

With reference to first row transition series. Among Zn^(+2) and Cu^(+2) which is colourless.

How would you account for the following: (i) Cr^(2+) is reducing in nature while with the same d-orbital configuration (d^4) Mn^(3+) is an oxidising agent. (ii) In a transition series of metals, the metal which exhibits the greatest number of oxidation state occurs in the middle of the series.

Which of the following halogens shows least number of oxidation states?
