Name two metals which are liquid at room temperature?

The two metals that are liquid at room temperature are mercury (Hg) and gallium (Ga). Most metals are solid at room temperature due to strong metallic bonding. However, some rare metals exist in liquid form or can melt very close to room temperature. These special cases are important in science, industry, and technology.

Mercury (Hg)

• Melting Point: -38.83°C
• Appearance: Shiny, silver-colored liquid metal.
• Uses: Thermometers, barometers, fluorescent lamps, dental amalgams.
• Danger: Toxic if inhaled or ingested.

Gallium (Ga)

• Melting Point: 29.7°C (can melt in the palm of your hand).
• Appearance: Silvery, soft metal.
• Uses: Semiconductors, LEDs, solar panels, medical thermometers.
• Safe: Less toxic compared to mercury.

Other Metals Close to Liquid State

• Cesium (Cs): Melting point 28.5°C.
• Francium (Fr): Predicted to be liquid near room temperature, but highly radioactive and rare.
