Mercury element in Periodic table
The Mercury element (Hg) has the atomic number 80 and is located in group 12 and period 6. Mercury is a liquid metal at STP and it is classified as a post-transition element.
Facts about mercury
Here are a few interesting facts about the mercury element.
- Mercury is a metal that is in liquid state at room temperature and pressure.
- Mercury is the 67th most common element present in the earth’s crust.
- Earth’s crust contains mercury in the concentration of only 80 parts per billion by weight.
- Mercury is largely produced in Spain and Italy.
- Mercury is toxic metal and it should not be touched with bare hands.
- Mercury is a dense liquid metal and it is 13.5 times heavier than water.
Properties of mercury
Here is a list of some physical properties and chemical properties of mercury.
Physical properties of mercury
- Mercury has a shiny metallic appearance and it is in liquid state at room temperature and pressure.
- Mercury forms small hemispherical droplets when it is spilled on the surface.
- Mercury has a rhombohedral crystal structure.
- The melting point and boiling point of mercury is 234.3 K and 629.8 K respectively.
- Mercury has many isotopes, and out of those isotopes the most abundant isotope is 202Hg.
Chemical properties of mercury
- Mercury is a toxic metal and it can damage our kidneys, levers, nerves, etc.
- Mercury can form amalgams with silver, tin and gold.
- If mercury is kept open in the moist air, then it will form an oxide layer on it.
- Mercury easily reacts with aluminum metal and it forms an oxide layer on aluminum. So mercury is not allowed in airplanes.
- Mercury does not show chemical reactions with iron, so it is generally stored in iron containers.
Uses of mercury
Here are some uses of the mercury element.
- Mercury is generally used in temperature measuring apparatus like thermometers.
- Mercury is also used in devices like barometers, manometers, etc which measures pressure.
- Mercury is also used to extract silver and gold from their ores. Because mercury can easily amalgamate (form alloy) with these metals.
