Instead, it tends to form cohesive droplets. Mercury has a very high surface tension, making it appear almost spherical when placed on a surface.ĭue to its high surface tension, mercury does not spread out like other liquids. Today, we understand the dangers of mercury exposure and have regulations to prevent such health issues.Ĥ. Hence, the term “mad as a hatter” emerged. This exposure led to neurological symptoms, including tremors, mood swings, and even hallucinations. In the 18th and 19th centuries, workers used mercury nitrate to treat the fur of small animals in hat manufacturing. Mercury’s toxic effects were historically observed in hat makers. Inhalation of mercury vapor can be toxic, leading to a condition known as ‘mad hatter disease.’ Historically, this has been an essential method for gold extraction, but it’s also environmentally hazardous due to mercury’s toxic nature.ģ. This amalgamation process is often used in gold mining.īy mixing mercury with crushed ore, it binds with gold to form an amalgam, which can then be heated to evaporate the mercury, leaving behind the gold. When mercury comes into contact with many metals, it forms an amalgam. Mercury is known to form amalgams with other metals, which has made it crucial in the extraction of gold and silver. Its chemical symbol, Hg, originates from the Greek word “hydrargyrum,” meaning “water silver.”Ģ. This property has made it particularly useful in various applications, including thermometers and barometers. Most metals are solid at these conditions. Mercury is unique among metals due to its liquid state at room temperature. Mercury is the only metal that is liquid at standard room temperature and pressure.
