  • What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support

    Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...

  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

  • Interesting facts about metals

    Metals have been used by people since ancient times. All the time the process of obtaining them was improved, useful alloys of various metals appeared. Let’s look at interesting facts about metals.

  • What are Compound Microscopes?

    Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

Delocalization

Of electrons, refers to bonding electrons that are distributed among more than two atoms that are bonded together, occurs in species that exhibit resonance.
The formation of a set of molecular orbitals that extend over more than two atoms, important in species that valence bond theory describes in terms of resonance.

Salicylaldehyde

An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.

Mass Deficiency

The amount of matter that would be converted into energy if an atom were formed from constituent particles.

Specific Heat

The amount of heat required to raise the temperature of one gram of substance one degree Celsius.

Conduction Band

A partially filled band or a band of vacant energy levels just higher in energy than a filled band, a band within which, or into which, electrons must be promoted to allow electrical conduction to occur in a solid.

Octahedral

A term used to describe molecules and polyatomic ions that have one atom in the center and six atoms at the corners of a octahedron.

Degenerate

Coefficient of expansion

The ratio of the change in length or volumen of a body to the original lengthor volume for a unit change in temperature.

Crystal Field Theory

Theory of bonding in transition metal complexes in which ligands and metal ions are treated as point charges, a purely ionic model, ligand point charges represent the crystal (electrical) field perturbing the metal?s d orbitals containing nonbonding electrons.
