Question

how does mercury differ from other metals? (1 point) it is not lustrous. it does not conduct electricity. it does not chemically react with other elements. it is not solid under normal conditions.

Explanation:

Most metals are solid at room temperature (normal conditions), but mercury (Hg) is a liquid. Let's analyze the options:

• Option 1: Metals are generally lustrous, and mercury is lustrous (it has a shiny appearance), so this is incorrect.
• Option 2: Metals are good conductors of electricity, and mercury, being a metal, does conduct electricity, so this is incorrect.
• Option 3: Mercury does react chemically with other elements (e.g., it can form compounds like mercuric oxide), so this is incorrect.
• Option 4: This is correct because unlike most other metals which are solid under normal conditions (room temperature and pressure), mercury is liquid.

Answer:

It is not solid under normal conditions.
