Assessment: JAMB UTME - Chemistry - 2012 Subject: Chemistry

Question 1 Report

Which of the following metals is the least reactive?
Answer Details
The least reactive metal among the options provided is Gold (Au). Gold is a noble metal and is generally unreactive, meaning it does not readily react with other substances. This is due to its electron configuration, which gives it a stable outer shell of electrons that is difficult to disturb. In contrast, other metals like lead (Pb), tin (Sn), and mercury (Hg) are more reactive than gold and can readily react with other substances, especially acids and oxygen in the air. Therefore, gold is often used in applications where a stable and unreactive metal is required, such as in jewelry and electronic components.
