Reaction with oxygen: No reaction (remains in the same state).
Reaction with water: Only some water-soluble forms dissolve. Becomes more toxic.
Combustible: Non-combustible
Reaction with light: No reaction with light.
Toxicity: Highly toxic.
Mercury is found in the group Transition metals( Metallic).
Group number: 12
Period number:6
First Cinnabar rock is mind from the crust. This rock contains Mercury Sulfide. Then for eliminating the Sulphur, the rock is heated to get pure Mercury(Hg). The Sulphur mixes with Oxygen and Mercury turns into vapor at its boiling point(356° Celsius). This vapor is then condensed to make liquid Mercury.
Common uses of Mercury in a regular household or within the society.
Mercury has high surface tension (it does not wet glass) makes it useful for the measurement of temperature in thermometers and of pressure in barometers and manometers.
It also has a, the high electrical conductivity which has led to its use in industrial power rectifiers, fluorescent sealed electric switches and relays, mercury-vapour lamps, mercury cell batteries.
Mercury is an ingredient in dental Amalgam fillings.
It is also widely used in Laboratories, Cosmetics, Advertising signs and Skin tanning lamps. It was previously used in the medicine field.

Mercury is a chemical element . It is commonly known as quicksilver. It got its name from the Roman God of trade, merchants, and travellers.
Cinnabar rock
Mercury's atomic number is 80. It has 80 electrons and 80 protons. But neutrons present are 121.
Manometer
Positives
Environment: Thermometers are used for determining the temperatures. In a way this is very useful, as temperature plays a great role while growing plants indoors.
Mercury's element symbol is Hg, which was derived from the word hydrargyrum. This is the Greek name for the element, and it stands for water-silver { "hydr-" water & "argyros" silver}.
Society: Countries exporting Mercury
earn a lot of profit beacuse of its high cost. This helps the Governmnet earn more income and work for the society's development.
Negatives
Health: Mercury was used in medicines, to heal fractures. And is still used in dental Amalgam fillings as well as thermometers.
Environment: Mercury is very poisonous, it is concentrated by fish and shellfish. When these fish are eaten by the fish high on the food chain they concentrate more of these toxic mercury. This could lead to various diseases/ cancer or maybe death.
Technology: The advertising signs are taking techno
logy to a new level as they shine bright at night with attractive colours, also very easy to read from far. These features are wanting people to buy more of those.
Society: The high price of this Mercury makes it
very hard to buy for common & poor man. This
also affects the economy of those countries which don't have Mercury resources.
Health: As we know fish tend to concentrate high amount of Mercury, and if this fish is consumed by a pregnant mother it can certainly by very harmful for her child's development. Direct intake can also lead to death.
CFL
Technology: As Mercury is very poisonous it was to be banned from being used in thermometers. Now the tech. industry had to find a replacement for Mercury which was a major obstacle which had to be overcomed by spending lots and lots of money and effort.
The atomic mass of Mercury is 200.592 which is approx 201. Number of protons(80) + Number of neutrons(121) = Atomic mass(201).
Bibliography:
Mercury is not a very active element, hence behaves like a noble gas and is highly resistant to chemical reactions and oxidation.
It will only combine at high temepratures with oxygen to form Mercury-oxide(HgO).
Mercuric Chloride (HgCl2) and Mercuric Fluoride(HgF2) are also mercuric compounds.
If found in vapor form mercury may form compounds with Argon, Xenon, Krypton and Neon.
Thermometer
Mercury is an extremely rare element in the Earth's crust.
It is either found as a native metal (which is very rare) or in , livingstonite, cinnabar, corderoite and other minerals, with cinnabar (HgS) being the most common ore.
Element may be found in an mercury ore which could be an ordianary rock.
Mercury is found in China. Kyrgyzstan and several other countries.
