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 seen as linked to 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 of the word alchemy, which referred to an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine. hydrogen bonds Van der Waals force bonds, ion-ion interaction, ion-dipole interaction etc. primary chemical bonds e.g covalent bonds, in which atoms share one or more electron(s) ionic bonds, in which an atom donates one or more electrons to another atom to produce ions ( cations and anions) metallic bonds and 2. There are two types of chemical bonds: 1. For example, chemistry explains aspects of plant chemistry ( 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 addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. 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. It is a natural science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. An oil painting of a chemist ( Ana Kansky, painted by Henrika Šantel in 1932)Ĭhemistry is the scientific study of the properties and behavior of matter.
