CHEMISTRY GLOSSARY

molecular lattice    →   molekularna rešetka

Molecular lattice is a crystal lattice made molecules bonded together by intermolecular forces.

face-centered cubic lattice    →   plošno centrirana kubična rešetka

Face-centered cubic lattice (fcc or cubic-F), like all lattices, has lattice points at the eight corners of the unit cell plus additional points at the centers of each face of the unit cell. It has unit cell vectors a =b =c and interaxial angles α=β=γ=90°.

The simplest crystal structures are those in which there is only a single atom at each lattice point. In the fcc structures the spheres fill 74 % of the volume. The number of atoms in a unit cell is four (8×1/8 + 6×1/2 = 4). There are 26 metals that have the fcc lattice.

face-centered orthorhombic lattice    →   plošno centrirana ortorompska rešetka

Face-centered orthorhombic lattice (orthorhombic-F), like all lattices, has lattice points at the eight corners of the unit cell plus additional points at the centers of each face of the unit cell. It has unit cell vectors a≠b≠c and interaxial angles α=β=γ=90°.

hexagonal lattice    →   heksagonska rešetka

Hexagonal lattice has lattice points at the twelve corners of the hexagonal prism and at the centers of the two hexagonal faces of the unit cell. It has unit cell vectors a=b≠c and interaxial angles α=β=90° and γ=120°.

lateral chain    →   postranični lanac

Lateral chain is a shorter chain of hydrocarbons which is connected to the main chain of hydrocarbon.

latex    →   lateks

Latex, also known as rubber or natural latex, is a milky fluid derived from the rubber tree. The latex is a colloid of caoutchouc (25-35%) dispersed in water (60-75%), which forms rubber by coagulation. The term is also applied to artificial emulsions of natural or artificial rubber, or of certain synthetic resins (such as polyvinyl acetate or polyvinyl chloride). It is used in a wide variety of consumer products, including rubber gloves, tubing, condoms, rubber bands, etc.

rhombohedral lattice    →   romboedarska rešetka

Rhombohedral (or trigonal) lattice has one lattice point at the each corner of the unit cell. It has unit cell vectors a=b=c and interaxial angles α=β=γ≠90°.

simple cubic lattice    →   jednostavna kubična rešetka

Simple or primitive cubic lattice (sc or cubic-P) has one lattice point at the each corner of the unit cell. It has unit cell vectors a = b = c and interaxial angels α=β=γ=90°.

The simplest crystal structures are those in which there is only a single atom at each lattice point. In the sc structures the spheres fill 52 % of the volume. The number of atoms in a unit cell is one (8×1/8 = 1). This is only one metal (α-polonium) that have the sc lattice.

simple monoclinic lattice    →   jednostavna monoklinska rešetka

Simple or primitive monoclinic lattice (monoclinic-P) has one lattice point at the each corner of the unit cell. It has unit cell vectors a≠b≠c and interaxial angles α=γ=90°≠β.

simple orthorhombic lattice    →   jednostavna ortorompska rešetka

Simple or primitive orthorhombic lattice (orthorhombic-P) has one lattice point at the each corner of the unit cell. It has unit cell vectors a≠b≠c and interaxial angles α=β=γ=90°.
