Stable derivatives include the chloride and nitrate. Like silver, mercury reacts with atmospheric hydrogen sulfide. As Mercury's interior cooled, it contracted and its surface began to deform, creating wrinkle ridges and lobate scarps associated with thrust faults. Ridges, or dorsa, are named for scientists who have contributed to the study of Mercury.

Thousands of prisoners were used by the Luo Xi mining company to establish new tunnels. Depressions or fossae are named for works of architecture. Craters on Mercury range in diameter from small bowl-shaped cavities to multi-ringed impact basins hundreds of kilometers across. The magnetic-field strength at Mercury's equator is about nT.

The diagram on

This is because, coincidentally, Mercury's rotation period is almost exactly half of its synodic period with respect to Earth. Mercury readily combines with aluminium to form a mercury-aluminium amalgam when the two pure metals come into contact. Iron is an exception, and iron flasks have traditionally been used to trade mercury. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity.

This would indicate an

Cinnabar sometimes alters to native mercury in the oxidized zone of mercury deposits. As a result, transits of Mercury across the face of the Sun can only occur when the planet is crossing the plane of the ecliptic at the time it lies between Earth and the Sun. The purest of these was gold, and mercury was called for in attempts at the transmutation of base or impure metals into gold, which was the goal of many alchemists. Applications The bulb of a mercury-in-glass thermometer Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications.

All four mercuric halides are known. Notably, they fill a wide ring surrounding the Caloris Basin. Mercury is a heavy, silvery-white liquid metal. Most of the remaining radioisotopes have half-lives that are less than a day.

The diagram on the right illustrates the effects of the eccentricity, showing Mercury's orbit overlaid with a circular orbit having the same semi-major axis. This would indicate an interaction between the magnetosphere and the planet's surface. Mercury fulminate is a detonator widely used in explosives. In the diagram the varying distance of Mercury to the Sun is represented by the size of the planet, which is inversely proportional to Mercury's distance from the Sun.

It is a standard in electrochemistry. Thus, to a hypothetical observer on Mercury, the Sun appears to move in a retrograde direction. Mercury was used to extract silver from the lucrative mines in New Spain and Peru.
