Mercury is inarguably one of the most, if not the most, captivating metals on the periodic table because of its unorthodox existence as well as its properties. The element mercury is a highly intricate metal that’s composition, history, and presence in modern science has keep it so prevalent for thousands of years until recently. In this essay, one will examine all components of mercury, both physical and chemical, as well as its history and modern life, in order to paint the reader a much more heightened and detailed picture of the eightieth element. In order to fully understand mercury and all of it complexities as well as, simply put, quirks, starting from the basics is crucial. Mercury, symbol Hg, is listed as number eighty on the periodic table, and has a mass of 200.592 atomic mass units (AMU); coincidentally, mercury has eighty protons as well as electrons by default. This number of electrons, more specifically valence electrons, makes mercury easily bondable with other elements, “namely gold, silver, and zinc” (Jefferson Lab, The Element Mercury). By subtracting the atomic number, 80, from the elements mass in AMU, Mercury is known to have 121 neutrons. As with almost every other element, the number of neutrons in this element differs either giving it a …show more content…
Stuart, Mercury, Chemicool). In compliance with these figures, mercury has a most unique state of matter at room temperature for a metal, liquid. Its lustrous silver color is the namesake of mercury, as well as its movability, because of its similarities to the planet, “with both names meaning quicksilver” (Agata Blaszczak-Boxe, 10 Uncommon Facts About Mercury). The irrefutably most important chemical property of this metal is its toxicity, especially to humans, which is where ‘mercury poisoning’ coins from. It also forms bonds with other heavy metals of-the-like
Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted
Sam Kean author of The Disappearing Spoon in order to characterize the periodic table as the one of the single most important achievements in human history describes, relates, and emphasizes the importance of the periodic table in the world around us. Depicting his childhood in the introduction, Sam tells the story of Mercury of how a single element connects to history, medicine, and even science. Although the periodic table is around us all the time Sam emphasizes the lack of teaching during his highschool career. Sam even tells the story of how the periodic table was completed and how it was delayed due to the fact of war. These stories and descriptions were implemented to show how a single element arranged in a certain way in the periodic
The Disappearing Spoon, written by Sam Kean, is a fascinating novel that discusses one of the most important items in all of science, The Periodic Table of Elements. Throughout the novel, Kean brings up the idea that elements found on the table are not always what they appear to be, and how different elements can play different roles in a persons life. Sam Kean was always fascinated by elements, long before he wrote this novel in 2010. When Kean was a young boy, he would get sick on several different occasions, and was so interested by mercury thermometers to the point where he would break the thermometer on purpose just so he could see how the small mercury balls would react with each other. While reading this interesting novel, I turned my attention to Chapter 11, which is titled “How Elements Deceive”.
The symbol “As” from the periodic table, belongs to the chemical element Arsenic. Its located in group 15, period 4, and is clasificat as semi-metals. Arsenic’s atomic number is 33, and has a density of 5.776 grams per cubic centimeter. Arsenic melting point is 1090 K (817°C or 1503°F) and the boiling point is 887 K (614°C or 1137°F). The element specific gravities are 1.97 and 5.73, they are respectively to his two solid modifications: yellow, and grey (or metallic). Arsenic’s appearance is steel grey, very brittle, crystalline, and is classified as a semi-metal since it has properties of both.
Mercury’s surface temperatures range from -180*C to 450*C (-290*F to 840*F). Temperatures that hot can melt iron, and other metals. The dramatic temperature difference on Mercury are not only because it is so close to the sun but, also by Mercury’s surface features. The places that are the coldest on Mercury and at the bottom of the craters and basins. The hottest are the places closest to the sun.
No other metal better illustrates the diversity of effects caused by different chemical species than does mercury. On the basis of chemical speciation, there are three forms of mercury: elemental, inorganic, and organic compounds.
While all atoms of the same element have the same number of protons, it is possible for atoms of one element to have different numbers of neutrons. Atoms of the same element with different numbers of neutrons are called isotopes . For example, all atoms of the element carbon have 6 protons, but while most carbon atoms have 6 neutrons, some have 7 or 8. Isotopes are named by giving the name of the element followed by the sum of the neutrons and protons in the isotope's nucl...
The Periodic Table is based around the Atomic Theory. Firstly people believed that everything was made up the four elements Earth, Fire, Wind, and Water. This theory evolved into everything being made up of atoms. Breakthroughs throughout history such as the discoveries of the nucleus, protons, neutrons and electrons have pushed this theory forward to where it is today.
Mercury has countless uses and is a very important element, “named after the planet Mercury. Mercury's chemical symbol comes from the Greek word hydrargyrum, which means "liquid silver."”(Gagnon). On the periodic table its atomic
I am going to discuss about the element known as gold in my assignment. To describe the element gold in simple terms, I can only say that it is an element (chemical element). This element is denoted by the symbol Au. It has an atomic number of seventy nine (79). I will describe quite a number of things concerning gold as an element. To begin with is:
Today when people think of heavy metal, they think of numerous rock bands such as Guns n’ Roses, AC/DC, or Led Zepplin. However the more health conscious person should think of heavy metals such as lead, cadmium, and mercury. The most common metal to come in contact with humans, with possibly the most serious effects, is mercury. Mercury is a natural substance that can be found in the environment. It is the only common metal that is a liquid at room temperature, but at high temperatures it can evaporate into a colourless, odourless vapour. For years, this type of mercury has been used in products such as thermometers, switches, batteries, jewellery, cosmetics and even dental fillings (VDH 2004). Although mercury use has decreased throughout the years, many households still contain products with mercury in them. The following paragraphs give reasons why the use of mercury has decreased throughout the years by describing the effects of mercury on the human body, how mercury gets in the human body, and the steps taken to prevent the effects of mercury on the human body.
The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed.
In chemistry, metals compose a great number of the periodic table elements. Each metal has its own characteristic mass,
Mercury, historically known as quicksilver, is a unique element, whose long history and characteristics are some to be marveled at. A silvery white transition metal, mercury has a high luster, giving it a mirror-like appearance. It is the only metal that remains liquid at room temperature, yet it is not wet. This is because of its inability to be absorbed by other substances; instead, when spilled, it forms small, spherical beads. These beads are highly mobile and tremble at the slightest touch.
There are eight planets in our solar system. The first planet closest to the sun is Mercury. Therefore, Mercury is the hottest planet. Mercury’s surface is cold. However, in the daytime Mercury can get as hot as 840 degrees fahrenheit, which is 450 degrees celsius. During night time the temperature can decrease to 275 degrees fahrenheit, or -170 degrees celsius. Mercury is the smallest planet. Mercury is the quickest planet to move around the sun. Its speed is approximately 112,000 mph along its elliptical orbit. Mercury can move around the sun in 88 days. There are craters in mercury, and scientist believe ice is in the craters.
