CHEMISTRY GLOSSARY
chemical element → kemijski element
Chemical element is a type of matter of which elementary matter is composed. Chemical element is composed of atoms with the same core charge.
monovalent element → monovalentni element
Monovalent element having a valence of one, such as the hydrogen.
polyvalent element → polivalentni elementi
Polyvalent element is a molecule which having more than one valence, for example oxygen is a divalent in H2O, nitrogen is a trivalent in NH3, carbon is a tetravalent in methane (CH4).
transuranium element → trasuranski element
Transuranium elements are elements with an atomic number higher than 92 (uranium’s atomic number). Transuranium elements are unstable and occur in extremely low concentrations in nature. Most are made artificially.
abundance of elements → rasprostranjenost elemenata
Elements in nature are mostly found in different compounds and, rarely, in the free (elementary) state. In Earth’s crust the most abundant of all elements is oxygen (with 49.5 %), then silicon (25 %), aluminium (7.5 %), iron (4.7 %), calcium (3.4 %), sodium (2.6 %), potassium (2.4 %), magnesium (1.9 %) and hydrogen (1.9 %). These nine elements make up almost 99 % of the Earth’s composition.
elementary particle → elementarna čestica
Elementary particle is one of fundamental particles of which matter is composed, such as the electron, proton or neutron.
elementary reaction → elementarna reakcija
Elementary reaction is a reaction that occurs in a single step. Equations for elementary reactions show the actual molecules, atoms, and ions that react on a molecular level.
elementary substance → elementarna tvar
Elementary substance is a simple and pure substance which can not be, by chemistry methods, decomposed further into simpler substances.
groups in periodic system of elements → skupine periodnog sustava
Periodic system of elements is divided into 18 groups of chemical elements. Elements belonging to the same group have a same number of valence electrons and similar chemical properties. Elements of main groups are in 1., 2., and in groups 13. to 18. Different groups of elements can be named according to the first element in the group (elements of boron group, elements of carbon group), or they have some special names (noble gases, halogenic elements, halyde elements, earthalkali and alkali metals).
