Question

The least reactive metal among the following is:

Options

• sodium

• silver

• copper

• lead

Answer 1

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.
