$Fe$

Vedclass · Answer

(A) The reactivity of metals is determined by their standard oxidation potential or their tendency to lose electrons. Among the given transition metals,$Fe$ (Iron) is the most reactive.$Fe$ readily undergoes oxidation in the presence of moist air to form hydrated iron$(III)$ oxide,commonly known as rust:$4Fe(s) + 3O_2(g) + xH_2O(l) \rightarrow 2Fe_2O_3 \cdot xH_2O(s)$In contrast,$Pt$ (Platinum) is a noble metal and is highly unreactive. $Ni$ and $Co$ are less reactive than $Fe$ under standard atmospheric conditions.

Which is the most reactive metal among the given options?
