Etymology

Description

It is a heavy, silvery and liquid metal belonging to the zinc group. It is used in thermometers, barometers and other scientific instruments. It is more reactive than zinc and cadmium and does not eliminate hydrogen in acids. It forms many organic mercury compounds and complexes.

Language Of Origin

Latin

Origin Of Word

The Latin name of the Roman god Mercury is Mercurius (the symbol Hg comes from the ancient name of the element, hydrargyrum. It is a combination of the Greek hydr- meaning "water" and argyros meaning "silver").

Meaning

Mercury

Symbol Origin

mythological

Etymological Description

Like the planet Mercury, it is named after the mythological Roman god Mercury, the god of speed and messenger of the gods. The symbol Hg comes from the Greek words hydor and argyros, which later became Latin hydrargyrum. Because it is liquid like water at room temperature and has a silvery metal sheen.

Production & Use

Sources

Almost all mercury is obtained from cinnabar or mercuric sulfide (HgS). Some red cinnabar sources contain so much mercury that drops of pure mercury can be found in random samples.

Uses

It is used in thermometers, barometers and batteries. It is also used in electrical switches and mercury vapor lighting products.
