Reactive ion

If an ion contains unpaired electrons, it is called a radical ion. Just like uncharged radicals, radical ions are very reactive. Just like uncharged radicals, radical ions are very reactive. Polyatomic ions containing oxygen, such as carbonate and sulfate, are called oxyanions . See more An ion is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by … See more Ions can be non-chemically prepared using various ion sources, usually involving high voltage or temperature. These are used in a multitude of devices such as mass spectrometers See more • Air ionizer • Aurora • Electrolyte • Gaseous ionization detectors • Ioliomics • Ion beam See more The word ion was coined from Greek neuter present participle of ienai (Greek: ἰέναι), meaning "to go". A cation is something that … See more Ions in their gas-like state are highly reactive and will rapidly interact with ions of opposite charge to give neutral molecules or ionic salts. Ions are also produced in the liquid or solid state when salts interact with solvents (for example, water) to produce … See more Denoting the charged state When writing the chemical formula for an ion, its net charge is written in superscript immediately after … See more WebMERIE, Magnetically Enhanced Reactive Ion Etching, is where a magnetic field is applied in a capacitively coupled plasma etcher.
