Los elementos: el mercurio

Mercury is a shiny, reflective metal that is liquid at room temperature and as rare as silver. It is extremely toxic, which is reflected in the phrase 'mad as a hatter,' originating from 19th-century hat makers who used mercury. Today, mercury is used in thermometers and batteries. Its density allows objects like steel screws to float on it, making it one of the most beautiful and elusive elements.
