Negative air ions - Wikipedia
网页Negative ion reaction equations. Negative air ions (NAI) are important air component, generally referring to the collections of negatively charged single gas molecules or ion clusters in the air. They play an essential role in maintaining the charge balance of the atmosphere. [1][2] The main components of air are molecular nitrogen and oxygen.
Ion - Wikipedia
网页An ion that has more electrons than protons, giving it a net negative charge, is named an anion, and a minus indication "Anion (−)" indicates the negative charge. With a cation it is just the opposite: it has fewer electrons than protons, giving it a net positive charge, hence the indication "Cation (+)".
Ion | Definition, Chemistry, Examples, & Facts | Britannica
网页Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells.
4.7: Ions - Losing and Gaining Electrons - Chemistry LibreTexts
网页Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions.
