Explain the following observation about the transition elements.
(i) There is in general an increase in density of the element from titanium (Z=22) to copper (Z=29).
(ii) There occurs much more frequent metal-metal bonding in compounds of heavy transition elements (3d series )

Explain the following observations about the transition/ inner-transition elements : (i) There is in general an increase in density of elements from titanium (Z=22) to copper (Z=29). (ii) There occurs much more frequent metal-metal bonding in compounds of heavy transition elements (3rd series). (iii) The members in the actinoid series exhibit a large number of oxidation states than the corresponding members in the lanthanoid sereis

(a) Complete the following chemical reaction equations : (i) MnO_(4(aq))^(-) + C_(2)O_(4(aq))^(2-) + H_((aq))^(+) to (ii) Cr_(2) O_(7 (aq))^(2-) + Fe_((aq))^(2+) + H_((aq))^(+) to (b) Explain the following observations about the transition/inner transition elements : (i) There is in general an increase in density of element from titanium (Z = 22) to copper ( Z= 29). (ii) There occurs much more frequent metal-metal bonding in compounds of heavy transition elements ( 3^(rd) series). (iii) The members in the actinoid series exhibit a larger number of oxidation states than the corresponding members in the lanthanoid series.

Three occurs much more frequently metal-metal bonding in the compounds of heavy transition elements (3d series ). Assign reason.

Why is ghere a general increase in density of elements from titanaium (Z=22) to copper (Z=29) ?

Why there is generally an increase in density of elements from titanium (Z = 22) to copper (Z = 29) in the first series of transition elements ?

Explain the following observation : There is a general increase in density from titanium (Z = 22) to copper (Z = 29).

Explain the following: There is an increase in density of elements from titanium (Z = 22) to copper (Z = 29) in the 3d series of transition elements.

Explain the following observations giving an appropriate reason for each. (i) The enthalpies of atomization of transmition elements are quite high. (ii) There occurs much more frequent matal-matal bonding in compounds of heavy transition metals (i.e, 3^(rd) series). (iii) Mn^(2+) is much more resistant then Fe^(2+) toawards oxidation.
