An ion is a charged particle that forms when an atom gains or loses electrons. Positively charged ions are called cations, and negatively charged ions are called anions. Ions play a crucial role in chemical reactions and are essential for various biological processes.
The positive oxidation number indicates the number of electrons an ion has lost, while the negative oxidation number indicates the number of electrons gained. The oxidation number provides information on the charge of the ion and its ability to form chemical bonds.
Ionic bonds form when one atom donates an electron to another atom, resulting in one positively charged ion and one negatively charged ion. The opposite charges attract, holding the ions together in a stable bond.
The equation describing the reaction between water and hydrochloric acid is: HCl + H2O -> H3O+ + Cl-. In this reaction, a hydronium ion (H3O+) and a chloride ion (Cl-) are formed.
The bromide ion, Br-, is a negatively charged ion formed when a bromine atom gains an electron. It is stable and typically exists in ionic compounds such as sodium bromide (NaBr) or potassium bromide (KBr). Bromide ions are not found as isolated ions in nature but are commonly found in seawater and mineral deposits.

An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
The positive oxidation number indicates the number of electrons an ion has lost, while the negative oxidation number indicates the number of electrons gained. The oxidation number provides information on the charge of the ion and its ability to form chemical bonds.
This atom gain two electrons and become an anion.
