CHEMISTRY GLOSSARY
absorption → apsorpcija
Absorption is a phenomenon that occurs when matter crosses from one phase to another passing through the border surface and in the other phase more or less monotonously distributes itself in a concentration higher than the one within the first phase.
acid-base indicator → kiselo-bazni indikator
Acid-base indicator is a weak acid or weak base, such as litmus, methyl orange or phenolphthalein, which changes colour when it gains or loses an H+ ion.
alkaloid → alkaloid
Alkaloids are basic nitrogen organic compounds (mostly heterocyclic) derived from plants and having diverse pharmacological properties. Alkaloids include morphine, cocaine, atropine, quinine, and caffeine, most of which are used in medicine as analgesics or anaesthetics. Some alkaloids are poisonous, e.g. strychnine and coniine, and colchicine inhibit cell division.
alpha rays → alfa-zrake
Alpha rays are a stream of alpha particles. Alpha rays rapidly dissipate their energy as they pass through materials. They were discovered by the British physicist Ernest Rutherford (1871-1937), a New Zealander by birth, in 1903.
AMU → AMU
AMU or atomic mass unit is a unit of mass used to express relative atomic masses. It is equal to 1/12 of the mass of an atom of the isotope carbon-12 and is equal to 1.66 033×10-27 kg. This unit superseded both the physical and a chemical mass unit based on oxygen-16 and is sometimes called the unified mass unit or the dalton.
anisotropy → anizotropija
Anisotropy is the property of molecules and materials to exhibit variations in physical properties along different molecular axes of the substance.
atomic clock → atomski sat
Atomic clock is an apparatus for standardizing time based on periodic phenomena within atoms or molecules (ammonia clock; caesium clock).
Avogadro, Amadeo → Avogadro, Amadeo
Amadeo Avogadro (1776-1856) is an Italian chemist and physicist that proposed a correct molecular explanation for Gay-Lussac’s law of combining volumes. His work provided a simple way to determine atomic weights and molecular weights of gases. He is published a theory about the movement of particles in gases that became known as Avogadro’s Law.
