CHEMISTRY PERIODIC TABLE DEFINITION HOW TO

Traditional chemistry starts with the study of elementary particles, atoms, molecules, substances, metals, crystals and other aggregates of matter. The current model of atomic structure is the quantum mechanical model. Modern principles Laboratory, Institute of Biochemistry, University of Cologne in Germany Alternately, al-kīmīā may derive from χημεία 'cast together'. This may have Egyptian origins since al-kīmīā is derived from the Ancient Greek χημία, which is in turn derived from the word Kemet, which is the ancient name of Egypt in the Egyptian language. The modern word alchemy in turn is derived from the Arabic word al-kīmīā ( الكیمیاء). Alchemy is often associated with the quest to turn lead or other base metals into gold, though alchemists were also interested in many of the questions of modern chemistry. The word chemistry comes from a modification during the Renaissance of the word alchemy, which referred to an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism, and medicine. The applications of various fields of chemistry are used frequently for economic purposes in the chemical industry. It has evolved, and now chemistry encompasses various areas of specialisation, or subdisciplines, that continue to increase in number and interrelate to create further interdisciplinary fields of study.

For example, chemistry explains aspects of plant growth ( 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 ( cosmochemistry), how medications work ( pharmacology), and how to collect DNA evidence at a crime scene ( forensics).Ĭhemistry has existed under various names since ancient times. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. Chemistry also addresses the nature of chemical bonds in chemical compounds. 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.

Chemistry is the scientific study of the properties and behavior of matter.
