Ionic conductivity — Ionic conduction in solids has been a subject of interest as early as the beginning of the 19th century. It was established by Michael Faraday (1839) that the laws of electrolysis are also obeyed in ionic solids like PbF2 and Ag2S. There were,… … Wikipedia
Ionic radius — The ionic radius, r ion, is a measure of the size of an ion in a crystal lattice. It is measured in either picometres (pm) or Angstrom (Å), with 1 Å = 100 pm. Typical values range from 30 pm (0.3 Å) to over 200 pm (2 Å).The concept of ionic… … Wikipedia
Ionic bond — [ noble gas electron configuration, and this electron enters the chlorine atom exothermically. The oppositely charged ions are then attracted to each other, and their bonding releases energy. The net transfer of energy is that energy leaves the… … Wikipedia
Ionic crystal — Light blue = Na+ Dark green = Cl An ionic crystal is a crystal consisting of ions bound together by their electrostatic attraction. Examples of such crystals are the alkali halides, including potassium fluoride, potassium chloride, potassium… … Wikipedia
Rydberg state — The Rydberg states of an atom are electronically excited states with energies that follow the Rydberg formula as they converge on an ionic state with an ionization energy. Although the Rydberg formula was developed to describe atomic energy… … Wikipedia

Oxidation state — Not to be confused with Oxidation number. In chemistry, the oxidation state is an indicator of the degree of oxidation of an atom in a chemical compound. The formal oxidation state is the hypothetical charge that an atom would have if all bonds… … Wikipedia
oxidation state — noun the degree of oxidation of an atom or ion or molecule; for simple atoms or ions the oxidation number is equal to the ionic charge the oxidation number of hydrogen is +1 and of oxygen is 2 • Syn: ↑oxidation number • Hypernyms: ↑number * * *… … Useful english dictionary
