Mercury Essay

Mercury is a heavy, silver-white, highly toxic metallic element. It is the only metallic element that is liquid at room temperature. Mercury can be used in thermometers, pesticides, pharmaceutical preparations, surfaces of mirrors, and dental fillings. There are several forms of mercury which include elemental or metallic mercury, inorganic mercury compounds, and organic mercury compounds. Elemental/metallic mercury is liquid at room temperature and turns into a colorless, odorless gas when heated

Mercury: The element mercury has the chemical symbol Hg; it is a silver colour and is a liquid at room temperature. Mercury has a high density and surface tension and can easily break up into small droplets. Mercury can dissolve some metals resulting in amalgams, metal alloys of mercury. It is not soluble in water or most other liquids, but will dissolve in lipids (fats and oils). With fluctuations in temperature, mercury expands and contracts evenly with these changes and is classed as a non-combustible

Mercury The surface of Mercury is littered with craters. These craters are believed to have been created by collisions from debris. Mercurys' craters range from small circular craters to multi-ridged impact basin. These basin are formed either when there was a large collision followed by a few small collisions or from many smaller collisions. The largest known crater on Mercury is called the Caloris Basin. This crater has a diameter of approximately 1500 kilometres across and surprisingly resides

The geology of Mercury is similar to the geology of the Moon. Although, Mercury is a much denser planet with a larger liquid iron core. The surface of Mercury is covered by impact craters. Although, only 55% of the Mercury has been mapped in enough detail to see its geology. Some of the largest craters were filled with lava from Mercury’s interior. Craters on Mercury can be small bowl-shaped pockets, or huge impact craters. The largest crater on Mercury is the Caloris Basin. There have been about

Mercury Mercury is a chemical element of heavy silver and white metal that is liquid at ordinary temperatures. The main use of mercury is the making of thermometers and barometers. Sometimes mercury is used as an electrode in the production of batteries. Mercury can be very toxic and harmful to the human body. If inhaled it can cause destruction to the nervous, digestive, and immune systems and can even be fatal. Mercury is found in many natural sources such as volcanos, forest fires, and fossil

am Buzzsonic I love Mercury!!!!!!! And I am going to tell you all about it. Did you know that Mercury has extreme seasons. The temperature range is 801 degrees fahrenheit to -297 degrees fahrenheit . Alien: Mercury has less gravity on it so if you weighed 100 pounds on earth you would weigh 38 pounds on Mercury. So you would be super light on Mercury compared to Earth. Alien: Mercury has a very thin atmosphere. I have only found a trace of atmosphere on Mercury. Also mercury has no weather. It has

Mercury is a transition metal that is also known as “quicksilver.” No one is sure who discovered this element. Mercury has been used since ancient times; the Chinese, Egyptians, and the Hindus have been known to use mercury. In 1500 B.C. mercury was found in ancient Egyptian tombs. There also has been writings found that have said “liquid-silver” and “water-silver” written by Aristotle in the fourth century B.C. The Greeks referred mercury as hydragyrum. The romans modified this name to Hg which

Mercury Poisoning The article “Our Preferred Poison” in the March 2005 issue of Discover magazine brings up the issue dealing with mercury poisoning. The author, Karen Wright, writes, “Mercury is unimaginably toxic and dangerous. A single drop on a human hand can be irreversibly fatal. A single drop in a large lake can make all the fish in it unsafe to eat.” This was the opening statement in the article which first grabbed my attention, because I had not thought mercury to be such a deadly

Consequences of Mercury Pollution Coming in Contact with Mercury People can come in contact with mercury in a number of ways. There is increased risk of mercury exposure in the dental, health and chemical industries. People are also at risk of consuming an unsafe amount of mercury if they eat certain things in excess amounts, such as more than 6 ounces of albacore tuna per week, or over 12 ounces of fish like shrimp, canned tuna, salmon, pollock or catfish. Exposure to mercury can cause brain

Planets on YouTube will help us to explore our options. This video looks at 6 other Planets that may or may not be possibilities of sustaining life. The first planet was Mercury. Mercury is the closest planet to the sun and one day on mercury lasts up to 58 days on Earth due to its slow rotation. There is one positive aspect of Mercury,

The element Mercury is a group 12, period 6 transition metal. Its atomic number is 80 and its atomic mass is 200.59. Mercury has a silvery, mirror-like appearance and is very dense. It weighs 13.6 times as much as the same volume of water (Blaszczak-Boxe, 2014). Mercury is the only common metal that remains a liquid at room temperature. Mercury is a monoatomic substance and is represented by the symbol Hg on the periodic table that comes from the Greek word hydrargyrum, which means “liquid silver”

plains, many a consequence of volcanic floods and pyroclastic deposits. Other important features of Mercury include vents which seem to be the cause of magma-carved valleys. They are often grouped togther in irregular-shaped depressions called "hollows" that are believed to be the aftermath of collapsed magma chambers, and mineral deposits inside craters at the poles. It was long thought that Mercury was geologically inactive however new evidence tells us there may be some level of life. The atmosphere

Introduction to mercury contamination: Mercury is a naturally occurring element, which is released from the earth’s crust through a number of pathways. For instance, natural erosion of mercury containing rocks enable its transportation into the air and be washed off to waterways. Volcanic eruptions and geothermal activity also release mercury. Therefore, there are natural background levels of mercury. However, anthropogenic sources of mercury emissions following the industrial revolution has increased

Introduction The planet Mercury is very difficult to study from the Earth because of its proximity to the Sun. It is the second smallest planet (it was believed to be the smallest until the discovery that Pluto is actually much smaller than originally thought), and also the fastest in its orbit since it is the innermost planet. Solar System Records Highest uncompressed density. Highest diurnal variation in temperature. Only Solar System object with a 3:2 spin-orbit resonance. it rotates on its

The name of our planet in Roman Mythology is the Roman god of commerce, travel, and thievery. Mercury is the closest planet to the sun, it rotates around the sun faster than any other planet in our solar system. It takes 1407.5 hours for it to rotate on its axis. Mercury is the smallest and innermost planet in our solar system. The radius of Mercury is 1,516 mi. Mercury’s mass is 3.285 times 10^23 kg. Mercury takes 88 days to rotate the sun completely. Mercury’s distance from the sun is 35.98 million

How is mercury contamination in aquatic ecosystems an environmental issue in Australia? Introduction to mercury contamination: Mercury is a naturally occurring element, which is released from the earth’s crust through a number of pathways. For instance, natural erosion of mercury containing rocks enable its transportation into the air and be washed off to waterways. Volcanic eruptions and geothermal activity also release mercury. Therefore, there are natural background levels of mercury. However

of the largest crater is the Caloris Basin, with the diameter of 1,550 km. The impact was so powerful that it caused lava eruptions and a concentrated ring over 2 km tall surrounding the basin to form. There are two distinct regions of plains on Mercury. These plains occur between the crater impacts and they bear a strong resemblence to the lunar maria. From the MESSENGER spacecraft, we were able to see that there

Mercury - Surface Geology Mercury's surface is heavily cratered. There are two distinct types of craters that can be observed on Mercury's surface; the more common impact crater - formed during asteroid impact, and pit craters - formed from the collapse of subterranean magma chambers. The former, impact craters, are typically more circular in shape and are accompanied by high ridges around the perimeter of the impact where debris from the impact was ejected. The latter, pit craters, are more irregular

The surface of Mercury is very rocky, and has many pits and craters on it due to the large number of meteors that have collided with the surface over the years. According to all all observations that muggle spacecraft has made, the surface of Mercury is dead, with no signs of life or liquid water. This is largely due to its lack of atmosphere and extreme temperatures. Also due to the lack of atmosphere, Mercury has no weather or wind, and the surface has few distinguishing features such as riverbeds

dust. The surface is also filled with craters. The planet is a grey color. It is the smallest planet but very dense. The surface of Mercury is very similar to the surface of the moon, but Mercury has more smooth plains. On Mercury you will not find any clouds, dust storms, rivers or any other sign of weather. The planets magnetic field keeps any winds away from it. Mercury has a mainly iron rich core. The planet will always be facing the sun on one side, lighting up half of its surface. The side facing
