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.

Dipole Moment

The product of the distance separating opposite charges of equal magnitude of the charge, a measure of the polarity of a bond or molecule, a measured dipole moment refers to the dipole moment of an entire molecule.

High Spin Complex

Crystal field designation for an outer orbital complex, all t2g and eg orbitals are singly occupied before any pairing occurs.

Colloid

A heterogeneous mixture in which solute-like particles do not settle out.

Forbidden Zone

A relatively large energy separation between an insulator's highest filled electron energy band and the next higher energy vacant band. Beginning in the fourth energy level, a set of seven degenerate orbitals per energy level, higher in energy than s, p, and d orbitals of the same energy level.

Hydrogen-Oxygen Fuel Cell

Fuel cell in which hydrogen is the fuel (reducing agent) and oxygen is the oxidizing agent.

 

Covalent Compounds

Compounds containing predominantly covalent bonds.

Hund's Rule

All orbitals of a given sublevel must be occupied by single electrons before pairing begins.

Heterocyclic Amine

Amine in which the nitrogen is part of a ring.

Eluant or eluent

The solvent used in the process of elution, as in liquid chromatography.
