Chemistry is a physical science that studies the spontaneous reactions that occur between two or more chemicals, or the chemical makeup of various organic and inorganic objects. Before chemistry came about in the 1700s, people studied alchemy, which was relatively similar but had less of a scientific basis. There are a number of... more »
There are a number of phenomena that occur naturally in the world around us but that our science is only now beginning to understand. One such occurrence is the formation of the hydrate, a chemical compound created with a number of different molecules and one common denominator: water. more »
Many people think film photography is simple. You load the film into the camera, point and shoot, right? While the process of taking a picture may seem simple on the outside, inside the camera and photo lab a complex chemical process is taking place. Learning more about this process will help you understand just how special taking a... more »
The atom is the most basic component of all the matter in the world. Atoms are made up of both positively charged protons and negatively charged electrons. Electrons move in large clouds around the nucleus of an atom and are notoriously hard to locate as they travel. Orbitals can be used in chemistry to find out information about... more »
Teaching any Advanced Placement (AP) class can be a challenge, but none more so than AP chemistry due to broadness of scope and depth of coverage. Independent of funding, effective teaching roots in the charisma and method of the instructor. The following advice is based on course evaluations written by chemistry students and proven... more »

Chemistry (from Arabic:الكيم Latinized: chem (kēme), meaning "earth")See: Chemistry (etymology) for possible origins of this word. is the science concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical reactions.. (n.d.). Merriam-Websters Medical Dictionary. Retrieved August 19, 2007. It is a physical science for studies of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes. Modern chemistry evolved out of alchemy and began to develop into its modern form through the 10th Century Arab world and following the chemical revolution (1773).
Disciplines within chemistry are traditionally grouped by the type of matter being studied or the kind of study. These include inorganic chemistry, the study of inorganic matter; organic chemistry, the study of organic matter; biochemistry, the study of substances found in biological organisms; physical chemistry, the energy related studies of chemical systems at macro, molecular and submolecular scales; analytical chemistry, the analysis of material samples to gain an understanding of their chemical composition and structure. Many more specialized disciplines have emerged in recent years, e.g. neurochemistry the chemical study of the nervous system (see subdisciplines).
Summary
Chemistry is the scientific study of interaction of chemical substances that are constituted of atoms or the subatomic particles: protons, electrons and neutrons. by Anthony Carpi, Ph.D. Atoms combine to produce molecules or crystals. Chemistry is often called "the central science" because it connects the other natural sciences such as astronomy, physics, material science, biology, and geology.Theodore L. Brown, H.
