A chemist (from Greek chēm(ía) alchemy; replacing chymist from Medieval Latin alchemist) [1] is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field. Chemists study the composition of matter and its properties.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Example sub-disciplines of chemistry include: biochemistry, the study of substances found in biological organisms; physical chemistry, the study of chemical processes using physical concepts such as thermodynamics and quantum mechanics; and analytical chemistry, the analysis of material samples to gain an understanding of their chemical ...
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria.
An academic discipline or field of study is known as a branch of knowledge. It is taught as an accredited part of higher education . A scholar's discipline is commonly defined and recognized by a university faculty.
Immunochemistry – is a branch of chemistry that involves the study of the reactions and components on the immune system. Chemical oceanography – study of ocean chemistry: the behavior of the chemical elements within the Earth's oceans. Mathematical chemistry – area of study engaged in novel applications of mathematics to chemistry. It ...
Environmental chemists draw on a range of concepts from chemistry and various environmental sciences to assist in their study of what is happening to a chemical species in the environment. Important general concepts from chemistry include understanding chemical reactions and equations, solutions, units, sampling, and analytical techniques. [1]
The late 20th century also saw an expansion of the application of analytical chemistry from somewhat academic chemical questions to forensic, environmental, industrial and medical questions, such as in histology. [7] Modern analytical chemistry is dominated by instrumental analysis. Many analytical chemists focus on a single type of instrument.
