Is mercury a chemical or physical property?

mercury (Hg), also called quicksilver, chemical element, liquid metal of Group 12 (IIb, or zinc group) of the periodic table.

What are the properties and uses of mercury?

Although many liquids could be used in pressure measuring devices, mercury is used because its high density requires less space. It is also a good conductor of electricity, so it is a useful component of electrical switches. Mercury is also used in dental fillings, paints, soaps, batteries, and fluorescent lighting.

What does mercury element do?

Mercury is used in many scientific instruments such as thermometers and barometers. Due to its electrical conductivity it is used to make silent switches, while its vapor form makes it useful in streetlights and fluorescent lamps.

What are 2 physical properties of mercury?

Mercury has a melting point of -38.9oC, a boiling point of 356.7oC, and is the only metal to remain in liquid form at room temperature. Droplets of liquid mercury are shiny and silver-white with a high surface tension, appearing rounded when on flat surfaces.

What are the properties of mercury Class 7?

Mercury is the only metal that is in liquid state at room temperature. It is used in thermometers because it has a high coefficient of expansion which makes it easy to move in the thermometers as per the temperatures. Mercury has a boiling point which makes it suitable to measure higher temperatures.

Why is mercury liquid 12?

According to this configuration of mercury, we see that all the subshells are completely filled due to which it resists the removal of an electron. This makes mercury similar to noble gas elements. Therefore, mercury forms a very weak bond and exists as liquid in room temperature.

Why mercury is a liquid metal?

Hence mercury cannot easily form bonds with other elements. This is the reason why mercury exists in a liquid state. It almost behaves like a noble gas because of the completely filled 6s orbital. In brief, Mercury is a liquid metal because it has a completely filled s-orbital.

What is mercury made of element?

Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide.

Is mercury flammable?

Mercury is non-combustible. The agent itself does not burn, but it may react upon heating to produce corrosive and/or toxic fumes. Fire will produce irritating, corrosive, and/or toxic gases.

Is mercury poisonous to touch?

Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.

What happens if mercury touches gold?

Freddie Mercury may have had the golden voice, but real mercury, that endlessly entertaining and dangerous liquid metal, has the golden touch. That is, if it touches gold it will immediately break the lattice bonds of the precious metal and form an alloy in a process known as amalgamation.

Is mercury toxic to breathe?

Elemental and methylmercury are toxic to the central and peripheral nervous systems. The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal.

Is liquid mercury illegal to have?

Effective January 1, 2003, the California Mercury Reduction Act banned the sale of many products containing mercury. Even though they are banned from California’s marketplace, these mercury containing products still are frequently found in homes.

Does mercury react with water?

Mercury does not react with water under normal conditions.

Does mercury burn your skin?

As long as you don’t expose your skin to the metal too much and you wash your hands after then you would be fine. If any mercury did absorb through your skin then the amount will be so small then you would urinate it out, leaving no mercury in your body and meaning it won’t build up to harmful amounts.

Can mercury from a thermometer hurt you?

Mercury vapor is not irritating and has no odor, so people do not know when they are breathing it. Even the small amount of mercury from a broken thermometer can cause harm, especially to children, unless it is properly cleaned up and removed.

What is mercury found in food?

King mackerel, marlin, orange roughy, shark, swordfish, tilefish, ahi tuna, and bigeye tuna all contain high levels of mercury. Women who are pregnant or nursing or who plan to become pregnant within a year should avoid eating these fish.
