What is an ion?

An ion is an atom or molecule that has a net electric charge due to the loss or gain of one or more electrons. If an atom loses electrons, it becomes positively charged and is called a cation. If an atom gains electrons, it becomes negatively charged and is called an anion. Ions play a crucial role in various chemical reactions and biological processes.

An ion is an atom or molecule that has lost or gained one or more electrons, resulting in a net electric charge. Ions are classified as either cations or anions. Cations have lost electrons and have a positive electric charge, while anions have gained electrons and have a negative electric charge. Ions are formed by the transfer of electrons between atoms or molecules, and are essential for many chemical and biological processes, such as:

- Chemical reactions: Ions are involved in many chemical reactions, such as acid-base reactions, redox reactions, and precipitation reactions.
- Biological processes: Ions are essential for many biological processes, such as nerve function, muscle contraction, and fluid balance.
- Industrial processes: Ions are used in a variety of industrial processes, such as electroplating, electrolysis, and battery manufacturing.
