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 … 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 … Meer weergeven Ions in their gas-like state are highly reactive and will rapidly interact with ions of opposite charge to give neutral molecules … Meer weergeven Ions can be non-chemically prepared using various ion sources, usually involving high voltage or temperature.
