\nThe reactivity of metals decreases as you move down the reactivity series. The reactivity series ranks metals based on their tendency to lose electrons and undergo oxidation. A metal higher in the series can displace a metal lower in the series from its salt solution. The standard reactivity series places Sodium (Na) very high, followed by Iron (Fe), then Copper (Cu), and finally Silver (Ag) is quite low. Therefore, the decreasing order of reactivity is Sodium, Iron, Copper, Silver.
\n<\/section>\n
\n– Metals are ranked by their reactivity (tendency to lose electrons).
\n– The reactivity series is K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Hg > Ag > Au > Pt.
\n– The metals in the options are Sodium (Na), Iron (Fe), Copper (Cu), Silver (Ag).
\n– Their order in the series is Na > Fe > Cu > Ag.
\n<\/section>\n
\nHighly reactive metals like Sodium react vigorously with cold water. Moderately reactive metals like Iron react with steam. Less reactive metals like Copper and Silver do not react with water or steam and are found uncombined in nature more often.
