Organic Chemistry Drawing Programs' title='Organic Chemistry Drawing Programs' />Chemistry Wikipedia. Chemistry is the scientific discipline involved with compounds composed of atoms, i. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds covalent bonds, in which compounds share one or more electrons ionic bonds, in which a compound donates one or more electrons to another compound to produce ions cations and anions hydrogen bonds and Van der Waals force bonds. Chemistry occupies an intermediate position in a hierarchy of the sciences by reductive level between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. Examples include plant chemistry botany, the formation of igneous rocks geology, how atmospheric ozone is formed and how environmental pollutants are degraded ecology, the properties of the soil on the moon astrophysics, how medications work pharmacology, and how to collect DNA evidence at a crime scene forensics. The history of chemistry represents a time span from ancient history to the present. Iseki Hydraulic Manual Transmission there. By 1. 00. 0 BC, civilizations used technologies that would eventually form the basis of the various branches of chemistry. Examples include extracting metals from ores, making pottery and glazes, fermenting beer and wine, extracting chemicals from plants for medicine and perfume, rendering fat into soap, making glass, and making alloys like bronze. The protoscience of chemistry, alchemy, was unsuccessful in explaining the nature of matter and its transformations. However, by performing experiments and recording the results, alchemists set the stage for modern chemistry. The distinction began to emerge when a clear differentiation was made between chemistry and alchemy by Robert Boyle in his work The Sceptical Chymist 1. While both alchemy and chemistry are concerned with matter and its transformations, chemists are seen as applying scientific method to their work. Chemistry is considered to have become an established science with the work of Antoine Lavoisier, who developed a law of conservation of mass that demanded careful measurement and quantitative observations of chemical phenomena. The history of chemistry is intertwined with the history of thermodynamics, especially through the work of Willard Gibbs. Chemistry was preceded by its protoscience, alchemy, which is an intuitive but non scientific approach to understanding the elements, compounds, and their interactions. It was unsuccessful in explaining the nature of matter and its transformations, but by performing experiments and recording the results, alchemists set the stage for modern chemistry. The distinction began to emerge when a clear differentiation between alchemy and chemistry was made by Robert Boyle in 1. Etymology. The word chemistry comes from alchemy, which referred to an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine. It is often seen as linked to the quest to turn lead or another common starting material into gold,6 though in ancient times the study encompassed many of the questions of modern chemistry being defined as the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies by the early 4th century Greek Egyptian alchemist Zosimos. An alchemist was called a chemist in popular speech, and later the suffix ry was added to this to describe the art of the chemist as chemistry. Software for the modern chemical laboratory including freezer software, chemical inventory, molecular modeling and drawing. Choosing the right program. As you choose a college, one of the biggest questions most students have is what to study. At Colorado State, we offer over 250 programs. Admission Requirements. Grade 12 with a minimum 60 in each of the following subjects English Language Arts A30, English Language Arts B30, Chemistry 30 and Pre. UNITS WITH SEVERAL PROGRAMS. Business is home to five programs, but is listed as one unit to the left. The Graduate Division of Biological and Biomedical Sciences is. The modern word alchemy in turn is derived from the Arabic word al km. In origin, the term is borrowed from the Greek or. This may have Egyptian origins since al km is derived from the Greek, which is in turn derived from the word Kemet, which is the ancient name of Egypt in Egyptian. Alternately, al km may derive from, meaning cast together. Modern principles. The current model of atomic structure is the quantum mechanical model. Traditional chemistry starts with the study of elementary particles, atoms, molecules,1. This matter can be studied in solid, liquid, or gas states, in isolation or in combination. The interactions, reactions and transformations that are studied in chemistry are usually the result of interactions between atoms, leading to rearrangements of the chemical bonds which hold atoms together. Such behaviors are studied in a chemistry laboratory. The chemistry laboratory stereotypically uses various forms of laboratory glassware. However glassware is not central to chemistry, and a great deal of experimental as well as appliedindustrial chemistry is done without it. A chemical reaction is a transformation of some substances into one or more different substances.

It can be symbolically depicted through a chemical equation, which usually involves atoms as subjects. The number of atoms on the left and the right in the equation for a chemical transformation is equal. When the number of atoms on either side is unequal, the transformation is referred to as a nuclear reaction or radioactive decay. The type of chemical reactions a substance may undergo and the energy changes that may accompany it are constrained by certain basic rules, known as chemical laws. Energy and entropy considerations are invariably important in almost all chemical studies. Chemical substances are classified in terms of their structure, phase, as well as their chemical compositions. They can be analyzed using the tools of chemical analysis, e. Scientists engaged in chemical research are known as chemists. Most chemists specialize in one or more sub disciplines. Several concepts are essential for the study of chemistry some of them are 1. Matter. In chemistry, matter is defined as anything that has rest mass and volume it takes up space and is made up of particles. The particles that make up matter have rest mass as well not all particles have rest mass, such as the photon. Matter can be a pure chemical substance or a mixture of substances. Atom. The atom is the basic unit of chemistry. It consists of a dense core called the atomic nucleus surrounded by a space hosting an electron cloud. The nucleus is made up of positively charged protons and uncharged neutrons together called nucleons, while the electron cloud consists of negatively charged electrons which orbit the nucleus. In a neutral atom, the negatively charged electrons balance out the positive charge of the protons. The nucleus is dense the mass of a nucleon is appromixately 1,8. The atom is also the smallest entity that can be envisaged to retain the chemical properties of the element, such as electronegativity, ionization potential, preferred oxidation states, coordination number, and preferred types of bonds to form e.

A chemical element is a pure substance which is composed of a single type of atom, characterized by its particular number of protons in the nuclei of its atoms, known as the atomic number and represented by the symbol Z. The mass number is the sum of the number of protons and neutrons in a nucleus.
