Identify the components of the alloy known as German Silver.

The period number and group number of Tantalum $(Z = 73)$ are respectively:

Which one of the following ions has the same number of unpaired electrons as those present in $V^{3+}$ ion?

Comment on the statement that elements of the first transition series possess many properties different from those of heavier transition elements.

Determine whether the following statements are True $(T)$ or False $(F)$:
$(a)$ Transition elements exhibit variable oxidation states.
$(b)$ The $E^o$ values for $Mn, Zn,$ and $Ni$ are more positive than expected from the general trend.
$(c)$ Any metal exhibits its maximum high oxidation state in oxide and chloride compounds.

Why do the transition elements exhibit higher enthalpies of atomisation?
