Mercury is a solid when given a pressure of 7640 atmospheres (5.8 million torrs). It dissolves in nitric or concentrated sulfuric acid but is resistant to alkalies. Mercury melts at -39C, boils at about 357C,and has a gravity of 13.5. The atomic weight of mercury is 200.59. Mercury comes in its pure form or combined with silver in small amounts.

Mercury, (HG) is a most unusual metal. It is the only common metal that occurs as a liquid at room temperature. This bright silvery, dense liquid- formerly known as quicksilver- has long held the fascination of people. Children sometimes play with the mercury from a broken thermometer, often with tr.
