Transition metals have high enthalpies of atomization.
Explain why Cr2+ is reducing but Mn3+ is oxidising while both ions have d4 configuration?
why do the transition elements show variable oxidation states?
Zn salts are white while Cu2+ salts are coloured. WHY?
1.why transition metals and their compounds act as a catalyst?
2.The outer electronic configurations of two members of the lanthanide series as follows:4f15d16s2 and 4f75d06s2.what are their atomic numbers?predict the oxidation states exhibited by these elements in their compounds?
1. explain why cu+ ion is not stable in aqueous solution?
2. explain why Ce4+ is a stronger oxidizing agent?
3. which is stronger reducing agent Cr2+, or Fe2+ and why?
4. Describe the oxidizing property of KMnO4 in neutral of alkaline medium for its reaction with iodide irons and thiosulphate irons.
5. What is magnetic moment of Cr3+ ion?
6. why do transition metals form alloys?
7. Why is V2+ is more Stable than V3+
what is lanthanoid and actinoids contraction?
Co2+ is easily oxidised to Co3+ ion in the presence of ligands .WHY?
what is meant by poor shielding effect ?
