How is the variability in oxidation state of transition metals different from these of p-block elements ?

(a) (i) How is the variability in oxidation states of transition metals different from that of the p-block elements? (ii) Out of Cu^+ and Cu^(2+) , which ion is unstable in aqueous solution and why? (iii) Orange colour of Cr_2O_7^(2-) ion changes to yellow when treated with an alkali. Why? (b) Chemistry of actinoids is complicated as compared to lanthanoids. Give two reasons.

How is the variablility in oxidation states of transition metals different from that of the non transition metals gt illustrate with example

How is the variability in oxidation states fo transition metals different from that of the non transition metaals? Illustrate with examples.

The variability of oxidation states of transition elements arises out of:

The properties of transition metals are in between the properties of __ block elements
