= *Valence Electrons: 2 = =*Discovered: Mercury was found by the Chinese and Hindus in tombs that were 3500 years old. Mercury is not found in nature but it’s obtained from the mineral cinnabar. = =*Chemical: Mercury is usually produced from cinnabar rock, also known as mercury ore. The rock contains mercury sulfide, which gives it its red color. To make pure mercury, you have to extract it from the cinnabar rock and eliminate the sulfur. The easiest way to do this is to heat the rock. The sulfur combines with oxygen and the mercury turns to vapor at a boiling point of 674 degrees F. The vapor is condensed to form liquid mercury.= =*Minerals: Mercury readily forms alloys with other metals, called amalgams. An electrical discharge will cause mercury to combine with the nobel gases argon, krypton, neon, and xenon. Mercury and its compounds are highly poisonous.= =* Physical: Mercury is a silvery mirror like liquid at room temperature and when cooled it becomes a tin white solid. Pure mercury has a high surface tenson and usually forms small bead like droplets when it is spilled.= =*Compounds: It only occurs as very small blobs on top of mercury ores such as cinnabar. Binary compounds with halogens, oxygen, hydrogen and some other compounds of mercury.= =*Reactions: Mercury metal reacts in air at about 350°C to form mercury(II) oxide ; Mercury metal reacts with fluorine, chlorine, bromine, or iodine, to form the dihalides mercury(II) fluoride= =*Uses: Mercury is used in laboratories for making thermometers, barometers, diffusion pumps, and many other instruments. It is used as an electrode in some types of electrolysis and for making batteries.= =*Cost: Mercury is a heavy metal that is freely found in nature in liquid form. The cost is about $5 per 100 grams of pure substance.= =*Bohr's model:= ==
