CHEMISTRY GLOSSARY

Lewis structure    →   Lewisova struktura

Lewis structure is the representation of the electron arrangement in atoms, ions, or molecules by showing the valence electrons as dots placed around the symbols for the elements.

Lewis acid    →   Lewisova kiselina

Lewis acid is an agent capable of accepting a pair of electrons to form a coordinate bond.

Lewis base    →   Lewisova baza

Lewis base is an agent capable of donating a pair of electrons to form a coordinate bond.

Lewis number    →   Lewisova značajka

Lewis number (Le) is a dimensionless quantity used in fluid mechanics, defined by

where a is thermal diffusivity and D is diffusion coefficient.

primary structure of proteins    →   primarna struktura proteina

Primary structure of proteins is a sequence of defined amino acids in some protein.

planary structure    →   planarna struktura molekule

Planary structure of molecule is a structure of molecule in which all atoms in the molecule lie in the same plane.

ringlike structure    →   prstenasta struktura

The ringlike structure is a structure by which the cycloalcanes and aromates are shown.

Lewis symbols    →   Lewisovi simboli

Lewis symbols are the shorthand electron dot structure of an atom.

condensed structural formulas    →   kondenzirane strukturne formule

Condensed structural formulas are shortened and easier layout of structural formulas of organic compounds (butane, CH₃(CH₂)₂CH₃).

structural isomer    →   strukturni izomer

Structural isomers are compounds that have the same formula, but different constituents. Dimethyl ether (CH₃OCH₃) and ethanol (CH₃CH₂OH), for example, are constitutional isomers with general formula C₃H₆O.
