Study Notes
Metals and Their Properties
- Tungsten has the highest melting point of all metals, at 3422°C (6192°F).
- Gallium is notable for being an exception to the general hardness of metals as it can melt just above room temperature, making it soft and malleable.
Liquid State of Metals
- Mercury and bromine are the only metals that exist in a liquid state at room temperature, with mercury having a melting point of -38.83°C (-37.89°F).
Physical Properties of Metals
- Sonority, the property responsible for the ringing quality of sound in metals, is attributed to their ability to vibrate when struck.
- The corrosion resistance of metals decreases due to exposure to atmospheric oxygen and moisture, leading to oxidation and rusting in certain metals like iron.
