Bromine And Fluorine Lab Report

Barium is a soft silver that is alkaline earth metal. Barium is never found in nature as a free element. The two of the most commonly natural occurring minerals of barium are as followed: barite, and witherite, they both very insoluble in water . Barium was soon identified as a new element back in 1774. Barium ended up not being reduced until 1808. Barium was beginning to be used as a “getter” for different vacuum tubes. Many barium compounds are added to fireworks so that the green color of fireworks can be seen. Barium is to be known as a insoluble additive to many oil wells and drilling fluids. The soluble barium ion and soluble compounds are extremely poisonous,

Lithium is the third element on the periodic table and is known as the lightest metal, and is half as dense as water. It is a part of the Alkali metals, meaning it is in the first group on the periodic table. Lithium is normally not found in nature, due to the fact that it has a very unstable nucleus. The name Lithium is derived from the Greek word lithos, which means “stone”. This name was likely given to Lithium due to the fact that it was discovered in the mineral petalite (LiAl(Si2O5)2) by Johann August Arfvedson in 1817. It was later isolated through the form of electrolysis of lithium oxide by William Thomas Brande. Lithium is made of two stable isotopes, with Lithium-6 containing 3 neutrons and accounting 7.59% of the natural abundance of lithium, and Lithium-7 containing 4 neutrons and accounting for 92.41% of lithium’s natural abundance.

Bromine is a chemical element with symbol Br and atomic number 35. Bromine is a red, brown liquid under standard conditions. Bromine atoms have an electron configuration of (2, 8, 18, 7) and 7 outermost shell electrons. Bromine is in group 17 and period 4 of the periodic table. Bromine commonly forms the anion Br- by receiving an electron, reaching a stable electron configuration. Bromine is a halogen.

Scientists at the Join Institute of Nuclear Research in Dubna, Russia and scientists at the Lawrence Livermore National Laboratory in California discovered element 117 or, tennessine, in 2010. With an atomic mass/weight of 294 making it the second heaviest element known to mankind behind element 118 or, Oganesson. Before being named tennessine by the International Union of Pure and Applied Chemistry (IUPAC) in 2016, tennessine had the place holder name of ununseptium, which means one-one-seven in Latin. Tennessine was created by fusing berkelium-249 atoms with calcium ions until tennessine atoms formed. Since tennessine is radioactive, it has zero stable isotopes. Tennessine’s most stable isotope, however, is tennessine, which has a half-life of about 80 milliseconds. Only six atoms of tennessine have been artificially created to this day.

Luminol (C8H7N3O2) is a chemical that can produce chemiluminescence, in a blue glow. Luminol is a white/pale yellow crystalline solid that is soluble only in the most polar organic solvents and insoluble in

It has an atomic mass of 51.996 amu, a melting point of 1907 degrees Celsius (2180 K, 3465 degrees Fahrenheit), and a boiling point of 2671 degrees Celsius (2944 K, 4840 degrees Fahrenheit). This element is the first element within group 6. The ways in which interactions with light occur along its surface allow for it to be considered lustrous. In addition, it is a silvery metallic that is hard yet brittle. Its crystalline structure consists of a body-centered cube. Its density is 7.19 g/cm3 at 20 degrees Celsius. Its electron configuration is 2-8-13-1. Its spdf configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^2 4s^2. It has electrons located in 4 energy levels. The most common ions chromium forms are Cr2+, Cr3+, and Cr6+.

The physical properties of neon include state,appearance,smell,density,boiling point,and melting point. The state is (20°c). The appearance is colorless,smell is odorless,the density is (.9g/l). The boiling point is (24.107k),and the melting point is (24.56k). Neon is also the second brightest noble gas after Helium. This element can also be watched using measurement or our human senses.

The element is colourless, odourless, tasteless and non-toxic. This makes it undetectable, as it is also inert and does not combine well with other elements. Helium is also extremely light (the 2nd lightest out of all the elements in fact). It is a monatomic gas (non-metal) with the lowest boiling and melting points among all the elements.

Element 95 on the periodic table, Americium was recognised in November 1945 by a chemist Glenn Seaborg who discovered the element as well as co-discovering ten other elements including Plutonium.1 The chemical element americium has atomic number 95 and an atomic weight of 243. Americium is a malleable, silvery white metal that tarnishes slowly in dry air at room temperature. . There are several known isotopes of americium and all of them are radioactive, the most stable being Americium -243 with a half-life of over 7500 years, although most common being Americium -241 with a half-life of 432.7 years, .2, 3, 4. Some of the isotopes of Americium include Am -237, Am- 238, Am -239, Am-240, Am-241, Am-242, Am-242m, Am-243, Am-244, Am-245 and Am-246.

Sense gallium is a metal, it is a good conductor. The boiling point of gallium is 2473 K (2200 Celsius). Its melting point is 302.91 K (29.76 Celsius). This element needs to be at a solid lab temperature. Gallium doesn't naturally occur in the earth's surface . It is created by other metals in the periodic table. A 100g of pure gallium cost is

In 1817, Swedish chemist, Johan Arfvedson discovered the element lithium while studying petalite ore. Lithium has been found in natural forms such as certain foods, water, and soil and in its purest form, it is a white powder. Lithium is isolated for commercial use from rocks and minerals. The element is located on the top left of the periodic table in the column of alkali metals, and like other alkali metals, it is highly toxic and flammable (Young, 2005). However, compared to the other alkali metals, it has a high melting point of 180 °C and a boiling point of 1347 °C (Young, 2007). The melting point is low compared to other metals, which makes lithium a favorable medium to transfer heat and is

Radium has the similar chemical properties as barium. Radium is very reactive. When it comes in contact with air, it violently reacts with it, turning from almost pure white to black, creating radium nitride. Radium can also react with water creating radium hydroxide. Radium also has other common compounds such as radium fluoride, radium bromide, radium chloride, radium oxide, radium iodide, radium nitride. Although radium is the heaviest member of the alkaline-earth metals it is the most volatile.

When surface tension at the air-liquid interface of the lung increases, such as during acute lung injuries, lungs can be filled with artificial oxygen-carrying fluids instead of air in order to reduce surface tension and facilitate ventilation. Also known as liquid ventilation (LV), LV is a form of mechanical ventilation in which the lungs are insufflated with an artificial oxygen carrier(s), such as oxygen-rich liquids, like perfluorocarbon and perflubrons, rather oxygen-rich gas mixtures (1). The perfluorocarbon liquids used to support pulmonary gas exchange is a type of synthetic liquid fluorinated hydrocarbons, or hydrocarbons with hydrogens replaced with fluorine atoms instead. Similar to perfluorocarbons, perflubrons are perfluorocarbon

most common element in the universe. It is a rare gas on earth. Helium was first discovered by Pierre Janssen in the spectrum of the sun during an eclipse in 1868. It was shortly identified as an element and was named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol of He. Helium is the second lightest element after Hydrogen and considered as the least reactive element. The more an element is reactive, the more flammable it is. It is considered a non-metal element with a number of 2 stable isotopes. It is a

My element is Boron. Boron compounds such as borax have been known and used by ancient cultures for thousands of years. Boron was first partially isolated in 1808 by French chemists Joseph L. Gay-Lussac and L. J. Thénard and independently by Sir Humphry Davy in London. Davy first tried to produce Boron by electrolysis of boric acid, but was not satisfied with how the results turned out. In 1909, American chemist Ezekiel Weintraub was able to produce 99% pure Boron, by reducing Boron halides with hydrogen. In 2004, Jiuhua Chen and Vladimir L. Solozhenko produced a new form of Boron, but were not certain of its structure. Boron is a tough element, very hard, and very resistant to heat. In its crystalline form, it is the second hardest element of all the
