Chemistry - the scientific study of substances, what they are made of, how they act under different conditions, and how they form other substances

Chemistry (from the Egyptian kēme (chem), meaning earth[1]) is the science that studies matter at the atomic to macromolecular scale, the reactions, transformations and aggregations of matter, as well as the energy and entropy released or absorbed during these processes. In short, chemistry studies molecules, crystals, and metals and is concerned with the composition and statistical properties of such structures, as well as their transformations and interactions to become materials encountered in everyday life. According to modern chemistry, the physical properties of materials are generally determined by their structure at the molecular or atomic scale, which is itself defined by interatomic electromagnetic forces, and laws of quantum mechanics and thermodynamics. Robert Boyle (1661), Antoine Lavoisier (1787), and John Dalton (1808) can be considered the three fathers of modern chemistry,[2] although other scientists have played a vastly important role, such as Dmitri Mendeleyev, Friedrich Woehler, Hermann Staudinger, to name but a few.

Chemistry - the study of atoms, made of nuclei (center particles) and electrons (outer particles), and the structures they form.

Chemistry is often called the "central science" because it connects other sciences, such as physics, material science, nanotechnology, biology, pharmacy, bioinformatics, and geology.[3] These connections are formed through various sub-disciplines that utilize concepts from multiple scientific disciplines. For example, physical chemistry involves applying the principles of physics to materials at the atomic and molecular level. The precise nature of the theoretical connection that chemistry (along with the other so-called special sciences) has with physics is a matter of research in philosophy of science.

Chemistry pertains to the interactions of matter. These interactions may be between two material substances or between matter and energy, especially in conjunction with the First Law of Thermodynamics. Traditional chemistry involves interactions between substances in chemical reactions, where one or more substances become one or more other substances.

The science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions

2007-03-17 18:54:34 · answer #7 · answered by p37ry 5 · 0 0

IT IS THE BRANCH OF SCIENCE
IT DEALS WITH THE systematic STUDY OF MATTER,IT'S PROPERTIES,AND COMPOSITION.

IT IS DIVIDED INTO SEVERAL TYPES:

1)INORGANIS CHEMISTRY:DEALS WITH THE ELEMENTS OTHR THAN CARBON

2)ORGANIC CHEMISTRY:)DEALS WITH THE DETAILED STUDY OF CARBON

3)ANALYTICAL CHEMISTRY:)PROPRTIES OF CERTAIN ELSEMENTS AND COMPOUNDS IN THE LABORATORY.

ORGANIC CHEMISTRY IS THE MOST INTERESTING ONE. (MY PREFERENCE)

the branch of science dealing with the elements and the compounds they form and the reactions they undergo and the study of chemical composition and properties of a substance

Half-life is the time by which half of the sample of a radioactive element disintegrates into some other element. Higher the rate of disintegation, lower is the half-life.
