What is the definition of a Chemist?
The word and occupation of "Chemist" can be different depending on where and in what context it is used. Generally speaking, a chemist studies and experiments with chemicals at the molecular and sometimes atomic level; focus is given to the chemical composition of substances and their reactions and relations to other substances. Chemists work with both organic and inorganic chemicals, and their studies and experiments inform many other fields of science, including medicine, environmental science, and forensic science. Chemists are vital to understanding how chemicals work alone and in conjunction with each other; work in chemistry has created powerful medicines and discovered previously unknown substances.
In some parts of the world, the word "chemist" is synonymous with "pharmacist" or "pharmacy," since each deals with chemical substances; the difference is that a pharmacist is not necessarily also a chemist, but one who implements pharmaceutical techniques.
A chemist is a scientist trained in the science of chemistry. Chemists study the composition of matter and its properties such as density, acidity, size and shape. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties.
Chemists use this knowledge to learn the composition, and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of sub disciplines of chemistry.
