Silver Oxide - Wikipedia
Like many silver compounds, silver oxide is photosensitive. It also decomposes at temperatures above 280 °C. Applications. This oxide is used in some silver-oxide batteries, as is the silver(I,III)oxide, Ag 4 O 4. In organic chemistry, silver oxide is used as a mild oxidizing agent. For example, it oxidizes aldehydes to carboxylic acids. ... Read Article

It is known that Al atoms are liable to release electrons partially due to their ... Access Full Source

Ionic Radius - Wikipedia
Ionic radius, r ion, is the radius of an atom's ion in ionic crystals structure. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice . ...
