Vedclass · Answer

(C) Transition elements are characterized by high melting points due to strong metallic bonding involving $d$-electrons. They exhibit variable oxidation states and many of their ions are paramagnetic due to the presence of unpaired $d$-electrons. However,not all transition elements dissolve in acids. For example,noble metals like $Au$ (gold) and $Pt$ (platinum) are chemically inert and do not dissolve in common mineral acids like $HCl$ or $H_2SO_4$.

Which of the following statements is $NOT$ consistent for transition elements?
