resonance effects: Used to describe the situation when a chemical species donates or withdraws electrons through orbital overlap with neighboring pi bonds. In resonance processes, electrons are delocalized and the energy of the electrons are stabilized. Pure substance – A substance made up of only one kind of matter; for instance, copper, distilled water and aluminum are all pure substances. But what do they mean? combination of a metal and non metal. Chemistry, basically, is the study of atoms, elements, compounds, and molecules. covalent bond: The sharing of electrons between to … Nucleus – In chemistry, the charged center of an atom; contains the atoms protons and neutrons. Density – Describes how compact a substance is, and is calculated by dividing mass by volume or D = m/v. 12. 3. acid any substance that dissociates in water to yield a sour corrosive solution containing hydrogen ions, having a pH of less than 7, and turning litmus red alcohol a colourless flammable liquid, the active principle of intoxicating drinks, produced by the fermentation of sugars, esp glucose, and used as a solvent and in the manufacture of organic chemicals. 20. 13. In anions, the degree of covalent bonding increases with increasing polarizability of the ion. Conductivity – Describes how easily a substance lets heat or electricity move through it. These are four terms to get you going. calorimetry - Calorimetry is the study of heat flow. 9. Chemistry is a physical science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions; it features an extensive vocabulary and a significant amount of jargon. oxidation state: Also known as the oxidation number, a measure for how many electrons an atom needs to become a neutral species. Metal – Typically, an element that is solid at room temperature, shiny, malleable, ductile, and a good conductor; for example, aluminum, iron, and calcium. Cite this article as: William Anderson (Schoolworkhelper Editorial Team), "General Chemistry: Key Terms & Definitions," in. Family – A vertical column of elements in the periodic table also known as a group. Not all reactions create the most thermodynamic product; some are controlled by kinetics instead. ionic compound. Chemical symbol – A short form used to represent the name of an element; C is the chemical symbol for carbon. 22. electrons in the outermost shell. Decomposition – A kind of reactivity that can break down a substance into its parts; for example, water can be broken down into hydrogen and oxygen by decomposition. 21. Periodic Table – A system for organizing the elements into columns and rows, so that elements with similar properties are in the same column. Science Teacher and Lover of Essays. Forms the basic understanding required to complete a calculation using the Born-Haber cycle. covalent bond: The sharing of electrons between to atoms, covalent bonds are typically quite strong. s-p hybridized orbitals are common for many organic carbon compounds. Look up definitions of common and important organic chemistry terms. 28. Your online site for school work help and homework help. Michael L. Matson is an assistant professor of chemistry at the University of Houston-Downtown where he instructs Inorganic Chemistry. substance. An example of a carboxylic acid is acetic acid. Alkalinity is a measure of how basic a substance is. Lustre – The ability to reflect light, or shine; silver has a high lustre and is so popular for jewellery; sodium metal is also lustrous. Calorimetry may be used to find the heat of reaction of two compounds or the heat of combustion of a compound, for example. There are many words and terms that are specific to chemistry, in this case inorganic chemistry. 1. 18. Here is a list of some of the most common and most interesting terms you need to know. Otherwise,... B Definitions - Background Radiation to Buffer. thermodynamic control: Reactions that create products with the lowest energy and most stable product are said to be controlled by thermodynamics. Important Chemistry terms. Molecule – A type of particle that is made up of two or more atoms bonded together; carbon monoxide is an example of a molecule. Professional writers in all subject areas are available and will meet your assignment deadline. Texture – Describes how the surface of a substance feels (its roughness, softness, or smoothness). chemistry: terms used in chemistry. They can be single, double, or triple bonds. 27. Precipitation – A solid substance that can form when certain dissolved substances are mixed together. 10. Atom – the smallest unit of an element that displays the same properties as the element, for example, hydrogen. 19. Chemical property – The ability of a substance to change or react and to form new substances when interacting with other substances, for example, zinc reacts with hydrochloric acid to produce hydrogen gas.
