Oxidation-Reduction Reactions - An Introduction to Chemistry
... Bonds between zinc atoms and oxygen atoms are lost in this reaction, so chemists say the zinc has been reduced. Like the term oxidation, the term reduction has been expanded to include similar reactions, even when oxygen is not a participant. The zinc ions in zinc oxide have a +2 charge, and the ato ...

Photophysical studies of formic acid in the VUV. Absorption
... The distinction between valence and Rydberg transitions is not always easy to establish since there can be quite a lot of mixing between valence and Rydberg states. Our analysis of the absorption spectrum of formic acid seeks to characterise those states that are predominantly valence or predominant ...

Electron configuration
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s2 2s2 2p6.Electronic configurations describe electrons as each moving independently in an orbital, in an average field created by all other orbitals. Mathematically, configurations are described by Slater determinants or configuration state functions.According to the laws of quantum mechanics, for systems with only one electron, an energy is associated with each electron configuration and, upon certain conditions, electrons are able to move from one configuration to another by the emission or absorption of a quantum of energy, in the form of a photon.Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements. The concept is also useful for describing the chemical bonds that hold atoms together. In bulk materials, this same idea helps explain the peculiar properties of lasers and semiconductors.
