An ion pair is a pair of ions, one positively charged and one negatively charged, that are attracted to each other due to their opposite charges. In chemical reactions, ion pairs can form when a molecule loses or gains an electron, creating ions with opposite charges that then attract each other to form a pair.

What is the role of the azide ion in chemical reactions?
The azide ion (N) acts as a nucleophile in chemical reactions, meaning it donates a pair of electrons to form new bonds with other molecules. It is commonly used in organic synthesis to introduce nitrogen-containing functional groups into compounds.
How does hydrogen become an ion in chemical reactions?
Hydrogen becomes an ion in chemical reactions by losing its single electron, leaving behind a positively charged hydrogen ion.
Is silver an ion?
Yes, silver can exist as an ion in certain chemical reactions.
Is gold an ion?
Gold is a metal, but it can form the Au3+ ion.
What best describes a Lewis base?
A Lewis base is a molecule or ion that donates an electron pair to form a covalent bond with a Lewis acid. It is often a species with a lone pair of electrons that can be shared with another atom to form a bond. Lewis bases are fundamental in coordination chemistry and are key players in many chemical reactions.

What are the properties and behavior of a doubly charged ion in chemical reactions?
A doubly charged ion in chemical reactions has a higher charge than a singly charged ion. This means it is more likely to attract or repel other ions or molecules in a reaction. The properties and behavior of a doubly charged ion can affect the overall outcome of a chemical reaction, as it can form stronger bonds or react more vigorously compared to a singly charged ion.
What is ion pairing and how does it affect chemical reactions?
Ion pairing is a phenomenon in which oppositely charged ions in a solution are attracted to each other and form pairs. This affects chemical reactions by altering the behavior of the ions involved, potentially slowing down or changing the outcome of the reaction.
Why ammonia is a Lewis base?
Ammonia is a Lewis base because it can donate a lone pair of electrons to form a bond with an electron-deficient species, such as a proton (H+) or a metal ion. This ability to donate electrons allows ammonia to act as a Lewis base in chemical reactions.
Does iodine gain electrons?
No, iodine typically gains electrons to form the iodide ion (I^-) in chemical reactions, as it has a tendency to pick up one electron to achieve a stable electron configuration.
What is true of a Lewis acid?
A Lewis acid accepts electron pairs.
How do you write sulfide?
The chemical formula for the sulfide ion is S2-. To write the sulfide ion in a compound, you would typically pair it with a cation (positively charged ion) to form an ionic compound, such as sodium sulfide (Na2S) or iron(II) sulfide (FeS).
What is a CO ion?
A CO ion is a carbonyl oxide ion, which is a molecule composed of a carbon atom and an oxygen atom with a triple bond between them. It is a reactive species that can participate in various chemical reactions.
