Which statement about metals at room temperature is true?

• A. Most metals are liquids at room temperature
• B. Most metals are gases at room temperature
• C. Most metals are plasmas at room temperature
• D. Most metals are solids at room temperature

Answer: (D)

At room temperature, which is around 20–25°C, most metals stay solid because their melting points are well above that temperature. The atoms in a metal are held together by strong metallic bonds in a dense crystal lattice, so it takes a lot of energy to break those bonds and melt the metal. Mercury is the notable exception—it is a liquid metal at room temperature. Metals aren’t gases or plasmas under normal conditions, so the statement that most metals are solids at room temperature is true.
