Synthetic elements

“F” on the periodic table. It is much more. In fact, fluorine is the most important element of any element on the periodic table. It indeed does not belong to the great collection of Noble Gases in Group 8A of the periodic table, but its position in Group 7A alongside the elegant Noble Gases solidifies it as one of the leading significant elements at our disposal. For that reason, in the the showmanship of element practicality, fluorine is an outstanding competitor! It truly displays admirable…

The history of piezoelectricity evolution is over 120 years which was discovered by brothers Curie in 1880. They were Pierre Curie (1859-1906) and Jacques Curie (1855-1941). During the study of the generation surface electrical charge by applying pressure on some material, they found out an unusual phenomenon which was a voltage of opposite polarity was generated by pressure was applied on the crystalline minerals such as quartz. The amplitude of the generated voltage was proportional to the…

Cerium is a rare earth element of the lanthanide series (atomic no. = 57– 71) of the periodic table. Among the various rare earth metals, cerium granted a hugeattention towards scientific community due to its catalytic antioxidant property. Usually, antioxidants protect cells from oxidative damage, mediated by ‘reactive oxygen species’ (ROS), which include free radicals such as superoxide anion (O2•-), hydroxyl radical (•OH), singlet oxygen (1O2) and non-free radical species like hydrogen…

Despite that silicon, iron and phosphate are distinct chemical elements, quartz and iron phosphate demonstrate very similar crystal structure, and this could be achieved through altervalent substitution based on the following equation: 2Si4+ → Fe3+ + P5+ As such, every two silicon ions in quartz is replaced by one iron(III)…

The CGS framework retreats to a proposition in 1832 by the German mathematician Carl Friedrich Gauss to base an arrangement of supreme units on the three essential units of length, mass and time. Gauss picked the units of millimeter, milligram and second The centimetre–gram–second arrangement of units (truncated CGS or cgs) is a variation of the metric framework taking into account the centimeter as the unit of length, the gram as the unit of mass, and the second as the unit of time. All CGS…

Crystalline and Amorphous Solids  Solids can be divided into two classes: crystalline and amorphous. Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures. Crystalline solids, or crystals, have distinctive internal structures…

Results and dissection 3.1 Transition metal complexes of the macrocyclic, H6L Ligand 3.1.1 The macrocyclic, H6L Ligand The physical and analytical data of the macrocyclic, H6L ligand and its transition metal complexes were shown in Table 1. From the investigation, the expected structure of H6L with its possible toutomeric forms can be represented as shown in Figure 1. H6L ligand is highly symmetric under the point group C2v symmetry and can show all the normal modes of vibrations by solving…

show why elements in similar group and period react differently. The purpose for this lab is to test the idea of patterns in the periodic trend, and if elements in similar group or similar period react differently due to the trend that they follow. If two elements in the same group or family are to be tested, one of the element reactivity will be slightly different from the other. This is the work of the periodic trends, the characteristics of an element atom change because of the element…

Discovered in 1898, the element neon has helped produce a staple of American cities and everyday night life: neon lights. Neon was first proved to exist by William Ramsay and Morris Travers of London, who decided to name the newly discovered element after the Greek word neos, or new. This finding was “vital in proving the existence of isotopes” (McCormick 1). The Periodic Table of Elements shows neon on the farthest right column, meaning it belongs to the noble gas family. As a part of the…

Chlorine is the second to lightest member of the halogen elements. It is in Group 17 (Group VIIA) and period 3 of the periodic table. The element symbol for Chlorine is Cl. Chlorine is a greenish yellow gas that is corrosive, toxic and can be irritating to the eyes and respiratory system. Chlorine is a nonmetal that has the atomic mass of 35.45 amu. It has a melting point of -100.98 degrees Celsius and a boing point of -34.6 degrees Celsius. However, at room temperature it is a gas. Chlorine…
