Translations for lattice energy Freebase(3.00 / 1 vote)Rate this definition: The lattice energy of an ionic solid is a measure of the strength of bonds in that ionic compound. It is usually defined as the enthalpy of formation of the ionic compound from gaseous ions and as such is invariably exothermic. Lattice energy may also be defined as the energy required to completely separate one mole of a solid ionic compound into gaseous ionic constituents.

- An ionic substance with a large lattice energy will generally have a higher melting point. LEWIS STRUCTURES. A covalent bond is a chemical bond formed by the sharing of a pair of electrons between atoms. A Lewis structure is a convention used to represent the covalent bonding in a molecule.Dots or lines are used to represent. valence electrons (electrons available for bonding).attice energy (lattice enthalpy) is the change in energy that occurs when an ionic solid is separated into isolated ions in the gas phase. In general, strength of ionic bonds and lattice energy are directly proportional. A large value in the lattice energy indicates a. strong ionic bond and vice versa.

- Lattice degeneration is a disease which affects the retina of the eye, causing the retina to atrophy and become thinner.n the United States, approximately 10% of the population suffers from lattice degeneration. Those who are nearsighted -- a condition also known as myopia -- can see nearby objects but things that are far away appear blurry. Lattice degeneration affects the retina of the eye.

Clathrate compound Clathrate compound. A clathrate is a chemical substance consisting of a lattice that traps or contains molecules. The word clathrate is derived from the Latin clatratus meaning with bars or a lattice. Traditionally, clathrate compounds are polymeric and completely envelop the guest molecule, but in modern usage clathrates also include host-guest complexes and inclusion compounds. According to IUPAC, clathrates are Inclusion compounds in which the guest molecule is in a cage formed by the host molecule or by a lattice of host molecules.

Cube In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 12 edges, 6 faces and 8 vertices. The cube is also a square parallelepiped, an equilateral cuboid and a right rhombohedron. It is a regular square prism in three orientations, and a trigonal trapezohedron in four orientations. The cube is dual to the octahedron.

- A crystal can be made of almost anything. Something is called a crystal if the atoms or molecules that make up the substance are arranged in a regular, periodic way. This regular arrangement is called a lattice. A common example of a lattice is a carton of eggs.

- Ionic lattice structure (General/Credit). Ionic compounds are made up of ions-positive and negatively charged particles. These positive and negative ions attract each other and group together in giant structures called lattices. In the lattice, each positive ion is surrounded by several negative ions.here is one easy method of breaking up the lattice, i.e., dissolve the ionic compound in water. Water has the ability to separate the ions from the lattice and allow them to move freely in solution. The lattice breaks up completely when it dissolves in water.

Lattice energy Sodium chloride crystal lattice. The lattice energy of a crystalline solid is usually defined as the energy of formation of the crystal from infinitely-separated ions, molecules, or atoms, and as such is invariably negative.ome older textbooks define lattice energy with the opposite sign, i.e. the energy required to convert the crystal into infinitely separated gaseous ions, atoms, or molecules in vacuum, an endothermic process. Following this convention, the lattice energy of NaCl would be +786 kJ/mol.

Lattice, Basis and Crystal A lattice that can be characterised in this way is referred to as a Bravais lattice. [2] All lattice points are equivalent, i.e. all properties remain invariant under translations by any vector →Tmno. Also, an observer sitting on one specific lattice point would see the same environment as when sitting on any other.

What is lattice? (Chemistry question)? Best Answer: Some ionic compounds, and metals, are bonded in a lattice. Metal atoms are never found by themselves, they are always in a lattice. The ions in these are fixed in position. Eg. of an ionic compound: NaCl - 6X6 lattice.This means that the molecules form as a cube.To every sodium ion, there are 6 chloride ions surrounding it.To every chloride ion, there are 6 sodium ions surrounding it.etal atoms are never found by themselves, they are always in a lattice.

- The lattice can have a profound influence on the material's properties. For example, below we see two crystals - graphite and diamond. They each contain only 1 kind of atom - carbon. The difference is in how those atoms are arranged.

- Crystal Grouped by Lattices (Shape). There are seven crystal lattice systems. You can view examples of each type by following one of the 'Elsewhere on the Web' links I have provided. 1  Cubic or Isometric-not always cube shaped! 2  You'll also find octahedrons (eight faces) and dodecahedrons (10 faces).

Retinal Detachment 1 Share Your Story. 2  Lattice degeneration of the retina is a type of thinning of the outside edges of the retina, which occurs in 7% to 10% of the general population. 3  The lattice degeneration, so-called because the thinned retina resembles the crisscross pattern of a lattice, often contains small holes.

Crystals and Lattices One way of doing this for the body-centered lattice is shown at the left. A corner point is joined with three nearest body points to give the basis vectors for a rhombohedral primitive unit cell. If repeated, it fills space just as the body-centered unit cell does, and gives exactly the same lattice.

Crystal A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

Crystal structure The smallest group of particles in the material that constitutes the repeating pattern is the unit cell of the structure. The unit cell completely defines the symmetry and structure of the entire crystal lattice, which is built up by repetitive translation of the unit cell along its principal axes.
