Transcript of Physical and Chemical Change- Mercury

Physical and Chemical Change:
Mercury


Mercury is one of the many elements of the Periodic table, it is classified as a liquid metal, it is a good conductor of electricity but not heat. 'Quicksilver' is another name for the element Mercury, it is a poisonous element which is quite heavy and its colour is silvery-white. The chemical properties of Mercury is:- the atomic weight is: 200.59, the atomic number is: 80, the melting point is: -38.83°C, the boiling point is: 356.73°C and the density of Mercury is: (per cm ³) 13.5336 grams. The evaporating point/heat is: 58.5. Mercury's natural form is a liquid at room temperatures or normal conditions.
Quick Fact:
The element Mercury has been found in 1500 BC, tombs in Egypt.

This is what Mercury looks like on the periodic table,
the Hg stands for Hydrargyrum which means liquid silver.

Quick Fact:
The Element Mercury is used in Thermometers because when the temperature rises, Mercury does too. This shows that there is a rise in teperature and when it is cool, Mercury contracts.

Molecular Structure
Quick Fact:

Mercuric Sulfide is used to make a red paint.
Quick Fact:
Mercurochrome used to be used for/as antiseptic. It is now off the shelves of the super market because it is considered dangerous.
Quick Fact:

Methylmercury is used for the preservation of seeds. These seeds are fed to animals.
Quick Fact:
Dimethylmercury is used for calibrating research equipment. An example of its usage is to calibrate the Nuclear Magnetic Resonance.
The Mad Hatter, in the story 'Alice in Wonderland' is mad because hat makers in the 19th century used to make felt hats using the element Mercury, it made them go mad because it is a poisonous element.
Thermometers: The tubes are made by the manufacturer and once they have the tube are sent to the receivers, they add the bulb at the bottom by heating it up and then they sealing it. They add the liquid by placing a vacuum that sucks hydrocarbon fluid and Mercury into the tube. They are now used with less Mercury.
It is bonded to a Mercury Ion
