Gallium Essay

As previously stated, mercury is number 80 on the periodic table of elements. It is a metal, a transition metal to be exact. It has a symbol of “Hg”, an atomic mass of 200.59, and there are 7 known stable isotopes

According to Silver (n.d.), the characteristics of silver is that it is a soft, white metal that occurs in nature in four forms. The first form is as a native element. The second is as a primary component in silver materials. The third is as a natural alloy with other metals. The fourth is as a trace to minor components in

n the year of 1879,Swedish chemist Lars Fredrik Nilson discovered an element called Scandium.Scandium was found in Uppsala,Sweden.Nilson was studying the rare earth metals and tried to divide the element ytterbium with using euxenite and gadolinite.A part of his method needed the preparation materials which reacted to form erbium nitrate.Nilson added heat to the nitrate and found that his sample had small quantities of a element no one has ever heard of with a low atomic weight.That unknown element soon became Scandium!Soon after his discovery,Nilson started studying the element and determined that Scandium’s atomic weight is about 44.In the year of 1937,Metallic Scandium was first prepared by Fischer and his collegaues.They performed electrolysis

solar system. The element Hg is used in thermometers and barometers and is also used a

When solid gold reaches the melting point of 1947.52 degrees it then become a liquid. while gold is in the liquid state the particles move at a clam rate because the particles are more evenly spread out. But when pressure is applied to to this then particles will move at a faster rate because they are being pressed

Thallium appears bluish gray in color and has a soft texture. It has a melting point of 578,3°F (303.5°C) and a boiling of 2,655°F (1,457°C). You can find this element to be a solid at 20°C, and its specific point of gravity is 11.85. There are two main isotopes of thallium: 203Ti and 205Ti, though 11 isotopes can be found; a total of 31 isotopes exist. Thallium is able to form TiOH with water (H2O). It can also dissolve in hydrochloric acid, dilute sulfuric acid, and nitric acid. It’s not highly flammable nor is combustible, though it can be set on fire when in dust form and can give of corrosive fumes. The chemical compounds of thallium include 3 chlorides (TiCI, TiCI2, TiCI3), 1 bromide (Ti4Br4), 2 iodides (TiI, TiI3), 2 oxides (Ti2O, Ti2O3), 1 sulfide (Ti2S), and one selenide

It was discovered by a man known as Friedrich Stromeyer from Göttingen University. He discovered it while trying to solve the problem which was brought up when apothecaries of Hanover, Germany, made zinc oxide. The zinc oxide was discolored instead of being pure white. Stromeyer traced the discoloration to a component which was not known to the world. He produced a blue-grey metal which he called Cadmium after the mineral. Cadmium comes from the latin word cadmia, meaning calamine. Calamine is zinc oxide which Cadmium originated from.

Have you ever considered how Mercury and Yttrium compare with one another? There are many ways in which these two elements can be compared and contrasted. These elements from the Periodic Table of Elements differ in size, one more than twice that of the other, however they also share many physical similarities. Their locations on the periodic table also contrast one another.

Mercury, represented by symbol Hg, is a naturally occurring element in the Earth’s crust. It is the only metal that is a liquid at standard temperatures and pressure. It is a heavy silver transition metal, with an atomic weight of 200.59 and atomic number 80. Mercury is found in the air, water, and soil; it can exist as metallic mercury, inorganic or organic mercury compounds. Metallic mercury is stable; it is barely reactive with its surrounding. Also, mercury has a high boiling point and is a poor conductor of heat and electricity. Due to its distinctive physical properties mercury is commonly used in thermometers, barometers, light bulbs, and other scientific instruments. Historically, mercury has been circulating as early as 1500 BC in Egyptian Tombs. Mercury has been utilized to treat all kinds of sicknesses including yellow fever and malaria in the 1500s. During the 1800s

Helium is very light so it is used in things such as balloons and zeppelins as is lighter than air so rises above it. Neon is also well known for helping make neon signs because when an electrical current is passed through it will glow an orangey red colour. Argon is used in lightbulbs as it does not react with the metal filament used in light bulbs as it is very inert. Xenon and Krypton are used in fluorescent light bulbs and also some photography equipment as it emits a very bright white light. Radon is used in chemotherapy to help cure cancer.

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”. Because of its mobility, Mercury is also known as quicksilver and was named after the fastest moving plant in the solar system (Chemicool.com, 2012). The Lewis structure of mercury can be seen in Figure A.

Tsavorite garnets are shiny green young gemstones with a reasonably long geological history. They were first discovered in 1967 by a British geologist named Campbell R. Bridges in the north-east of Tanzania Mountains. Bridges came across strange bumps of rock and inside these objects were found to be some green grains and crystal fragments. Once gemmological examinations had been done on the rock, Bridge realised that he had discovered a green grossularite, which is a known mineral belonging to the garnet gemstone group.

Lawrencium is number 103 on the periodic table Lawrencium got its named after Ernest O. Lawrence the man who discovered the cyclotron a device used to to discover many artificial radioactive elements , was also found in the Lawrence Radiation Laboratory in Berkeley California 1961. This element is the most stable isotope ,Lawrencium has a half life of about 4 hours . Only tiny amounts of Lawrencium have been produced so there no use for it outside of scientific research , the atoms of the element is very small and by Lawrencium having a low half life it does not 't really give scientists a chance to research the element so this means scientists really do not know much about this element . Lawrencium boiling point is 2,960 degrees fahrenheit

The first point to note is that ‘inventor’ is a very ambiguous term. Is this the first person to think, to document, to patent, or to produce? The second point is that stainless steel wasn’t truly defined until 1911, so are we to cast aside those chromium-iron alloys that

To begin with, germanium is used in the manufacture of wide-angle camera lenses. The element gives special properties to the glass. Since, germanium has traits that are similar to silicon and tin, the semiconductor industry uses germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps. In other words, germanium is used to make camera lenses for electronic
