प्रश्न
The least reactive metal among the following is:
पर्याय
sodium
silver
copper
lead
Advertisements
उत्तर
Silver
Explanation:
According to the metal reactivity series, the reactivity of these elements decreases in the order of Sodium > Lead > Copper > Silver. Silver is placed near the very bottom of the series because its stable electron configuration makes it highly resistant to oxidation and corrosion. Consequently, it is a noble metal that does not readily lose electrons or react with water and acids compared to the other options
