Which element from the following is $NOT$ considered a transition element on the basis of electronic configuration?

Arrange the following ions in the increasing order of their magnetic moments: $(i) \, V^{4+}$,$(ii) \, Mn^{4+}$,$(iii) \, Fe^{3+}$,$(iv) \, Ni^{2+}$. $[V = 23, Mn = 25, Fe = 26, Ni = 28]$

The higher number of unpaired electrons are in

Transition elements are more metallic than representative elements ($s-$ and $p-$ block elements) due to

Which of the following ionic species will impart colour to an aqueous solution?

Out of $Cu_{2}Cl_{2}$ and $CuCl_{2}$,which is more stable and why?
