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 convention. The net charge of an ion is not zero because its total number of … Meer weergeven The word ion was coined from Greek neuter present participle of ienai (Greek: ἰέναι), meaning "to go". A cation is something that moves down (Greek: κάτω pronounced kato, meaning "down") and an anion is … Meer weergeven Denoting the charged state When writing the chemical formula for an ion, its net charge is written in superscript immediately after the chemical structure for the molecule/atom. The net charge is written with the magnitude before the sign; that is, a … Meer weergeven 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 … Meer weergeven 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, optical emission spectrometers, particle accelerators, ion implanters, … Meer weergeven • Air ionizer • Aurora • Electrolyte • Gaseous ionization detectors Meer weergeven Web1 aug. 2013 · Positive ions therefore also have a lower diffusivity, and this is balanced by a higher concentration of positive ions so that the actual removal rate by diffusion is the same for both positive and negative ions. The actual values of the ion concentrations depend strongly on the concentration of aerosols or pollutants.
