What are the elements and compounds found in the industry?
Compare and contrast elements and compounds Elements: Elements are the basic substances out of which all matter is composed. Everything in the world is made up from only 109 different elements. 90% of the human body is composed of only three elements: Oxygen, Carbon and Hydrogen Elements are known by common names as well as by their abbreviations. These consisting of one or two letters, with the first one capitalized. These abbreviations are derived from English or foreign words (e.g. Latin, German). A chemical element, or element for short, is a type of atom that is defined by its atomic number; that is, by the number of protons in its nucleus. The term is also used to refer to a pure chemical substance composed of atoms with the same number of protons.[1]Common examples of elements are hydrogen, nitrogen, and carbon. In total, 117 elements have been observed as of 2007, of which 94, i.e. plutonium and below, occur naturally on Earth. Elements with atomic numbers greater than 82 (i.e., bismuth and those above), are inherently unstable and undergo radioactive decay. In addition, elements 43 and 61 (technetium and promethium) have no stable isotopes, and also decay. However, the unstable elements up to atomic number 94 with no stable nuclei are found in nature as a result of the natural decay processes of uranium and thorium. [2] All chemical matter consists of these elements. New elements are discovered from time to time through artificial nuclear reactions.The term 'elements' (stoicheia) was first used by the Greek philosopher Plato in about 360 BC, in his dialogue Times, which includes a discussion of the composition of inorganic and organic bodies and is a rudimentary treatise on chemistry. Plato assumed that the minute particle of each element had a special geometric shape: tetrahedron (fire), octahedron (air), icosahedron (water), and cube (earth).[3]Tetrahedron (fire) Octahedron (air) Icosahedron (water) Cube (earth) Adding to the four elements of the Greek philosopher Empedocles, in about 350 BC, Aristotle also used the term "element" and conceived of a fifth element called "quintessence", which formed the heavens. Aristotle defined an element as: Element - one of those bodies into which other bodies can be decomposed and which it self is not capable of being divided into other. [4]In 1661, Robert Boyle showed that there were more than just four classical elements as the ancients had assumed.[5] The first modern list of chemical elements was given in Antoine Lavoisier's 1789 Elements of Chemistry, which contained thirty-three elements, including light and caloric. By 1818, Jöns Jakob Berzelius had determined atomic weights for forty-five of the forty-nine accepted elements. In 1869, in Mendeleev's famous periodic table, shown below, there were sixty-six elements.Mendeleev's 1869 periodic tableFrom Boyle until the early 20th century, an element was defined as a pure substance that cannot be decomposed into any simpler substance.[5] Said another way, an "element" cannot be transformed into other chemical substances by chemical processes. In 1913, Henry Moseley discovered that the physical basis of the atomic number of the atom was its nuclear charge, which eventually led to the current definition. The current definition also avoids some ambiguities due to isotopes and allotropes. By 1919, there were seventy-two known elements.[6] In 1955, element 101 was discovered and named mendelevium in honor of Mendeleev, the first to arrange the elements in a periodic manner. In October of 2006, the synthesis of element 118 was reported; however, element 117 has not yet been created in the laboratory. Description:The lightest elements are hydrogen and helium. All the heavier elements are made, both naturally and artificially, through various methods of nucleosynthesis, including occasionally nuclear fission.As of 2006, there are 117 known elements (in this context, "known" means observed well enough, even from just a few decay products, to have been differentiated from any other element).[7][8] Of these 117 elements, 94 occur naturally on Earth. Six of these occur in extreme trace quantities: technetium, atomic number 43; promethium, number 61; astatine, number 85; francium, number 87; neptunium, number 93; and plutonium, number 94. These 94 elements, and also possibly element 98 californium, have been detected in the universe at large, in the spectra of stars and also supernovae, where short-lived radioactive elements are newly being made. The remaining 22 elements not found on Earth or in astronomical spectra have been derived artificially. All of the solely-artificially derived elements are radioactive with very short half-lives; if any atoms of these elements were present at the formation of Earth, they are extremely likely to have already decayed, and if present in novae, have are in quantities too small to have been noted. Technetium was the first purportedly non-naturally occurring element to be synthesized, in 1937, although trace amounts of technetium have since been found in nature, and the element may have been discovered naturally in 1925. This pattern of artificial production and later natural discovery has been repeated with several other radioactive naturally-occurring trace elements.Lists of the elements by name, by symbol, by atomic number, by density, by melting point, and by boiling point as well as Ionization energies of the elements are available. The most convenient presentation of the elements is in the periodic table, which groups elements with similar chemical properties together.

For example, pure water is composed of the elements hydrogen (H) and oxygen (O) at the defined ratio of 11 % hydrogen and 89 % oxygen by mass. The observation that the elemental composition of a pure compound is always the same is known as the law of constant composition (or the law of definite proportions). It is credited to the French chemist Joseph Louis Proust (1754-1826). A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of. A chemical formula is used a quick way to show the composition of compounds. Letters, numbers, and symbols are used to represent elements and the number of elements in each compound.Substances are either elements are compounds. Elements are substances in their simplest form that cannot be separated further through chemical reactions. Examples of elements are oxygen (O2), carbon (C2), and hydrogen (H2). Compounds are compositions of two or more elements. Examples or compounds are water (H2O), carbon dioxide (CO2), and sodium chloride - table salt (NaCl). Elements are materials that cannot be reduced further whereas compounds can be. Compounds do things by interacting with their environments, elements remain inert.
