Reactivity Series: Highest Metal
The reactivity series ranks metals based on their tendency to lose electrons and react. Metals higher in the series are more reactive.
Metal Positions in Reactivity Series
Comparing the given metals:
- Sodium (Na): Is a highly reactive alkali metal, placed very high in the series.
- Copper (Cu): Is a relatively unreactive transition metal, placed much lower.
- Silver (Ag): Is also an unreactive metal, placed below copper.
- Gold (Au): Is one of the least reactive metals, found at the bottom of the series.
The general order for these metals from most reactive to least reactive is: Sodium > Copper > Silver > Gold.
Conclusion on Reactivity
Based on its position, Sodium is the metal placed highest in the reactivity series among the choices provided.
