Abundance of the chemical elements

obtained from chemical compounds. This curiosity was noted previously by Henry Cavendish, but it remained anonymous. ("Neon," 1999). In 1898, a Scottish chemist Sir William Ramsay (1852-1916) and English chemist Morris M. Travers (1872-1961) discovered neon just after they discovered the element krypton that same year. ("Neon," 2000). Physical Description Neon is the second element in Group 18 of the periodic table, a group of elements known as the inert or noble gases. Neon’s chemical…

much blame for the nasty occurrence. In fact, this mother of repulsive odors earns its spot on the periodic table as one of the world's 118 chemical elements, or substances that contain only one type of atom. Much like any other non-metal, it does not retain the typical physical and chemical properties of metals, such as luster. The tenth most abundant element in the universe, sulfur additionally sports a multitude of unique characteristics- some even establishing it as an essential ingredient…

is an element that many people have either felt or seen without realizing it. Pennies, for example, are made of copper. Certain pipes, contraceptives, and wires are other ways copper is used in our daily lives. It 's a great conductor of electricity, antibacterial, and corrosion resistant. However, this raises the question: what exactly are the properties of copper that give it its properties? An element is a chemical substance in its simplest form. An atom is the basic unit of a chemical…

Atoms are what make up what we call “matter.” They are the smallest units of a chemical element, and they consist of protons, neutrons, and electrons. These components form an atom’s subatomic particles. Before discussing the copper atom at length, we must first be able to understand the components that comprise an atom. The first of these components that make up an atom is the proton. The proton is a very important part of an atom, because the atomic number of an atom is equivalent to the…

Gallium is one of those elements that is used in industry every day. Gallium was discovered in Paris at the private laboratory of Paul-Emile Lecoq de Boisbaudran (1831-1912) at 3 a.m. on August, 1875. He observed a new violet line in the atomic spectrum of some zinc he had extracted from a sample of zinc blende ore (ZnS) from the Pyrenees. He knew it meant that an unknown element was present. Gallium comes from Gallia, the Latin name for France. Gallium also has origins in the Latin word Gallus.…

Selenium: The Essential Element Introduction Over the years, selenium is known to be the essential element in all forms of life. Selenium is a metalloid belonging to the block p, group 16, period 4. It is a gray metallic rare element widely distributed within Earth’s crust which has an atomic number of 34 and a symbol “Se”. Selenium was discovered in 1817 by Jöns Jacob Berzelius and Johan Gottlieb Gahn after analysing an impurity contaminating the sulphuric acid being produced by a factory…

Research Paper John Murray like most scientists was not really appreciated while he was an alive but his discoveries were a major help after he died. He lived in a time that scientific discoveries were plentiful so it was extremely east for something like the study of oceanography to be overlooked. His discoveries lead to him being called the father of Oceanography (Sir John Murray-Founder of Oceanography). He was born in Canada in 1841 to Scottish parents. He soon moved to Edinburgh,…

knowingly) shaped by elements. In The Disappearing Spoon, the author Sam Kean, discusses the wonderful world of the periodic table in depth. Within the first nine chapters of the novel, Kean explains the importance of location on the table, origin and discovery of each element, and its impact on other aspects of human life. Through various tales, the table is pulled apart and analyzed in an ingenious way. To a reader, it is interesting to follow how our life is determined by the elements of the…

Beryllium General Characteristics According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to…

Definitions: 1. Atoms: According to Dalton’s atomic theory, atoms are the basic units of matter and the defining structure of elements. Atoms are made up of three parts: protons (positively charged), neutrons (uncharged) and electrons (negatively charged). For example: Sodium ( ) has 11 protons, 12 neutrons and 11 electrons. 2. Molecule: Molecules form when two or more atoms form chemical bonds with each other. It doesn’t matter if the atoms are the same or are different from each other. For…
