A chemical species known as an ion is one that has a noticeable positive or negative charge.
- Atoms or molecules having associated net charges greater than zero are referred to as “ions.” As a result, all ions either have more protons than electrons overall in their atomic or molecule structure.
- It is well known that ions with more protons than electrons have a net positive charge.
Types Of Ion
- In chemistry ions can be Cation or Anion.
- Cations are positively charged, whereas anions are negatively charged ions.
- It’s crucial to remember that the electrostatic forces of attraction between positively charged cations and negatively charged.
- Anions are what cause ionic bonds to form.
- Ionic compounds are formed from the type of chemical that results from the formation of an ionic bond between two oppositely charged ions.
How Do Ions Form?
Ions can be prepared in a variety of ways.
- One of the electrons on an atom or molecule may be knocked off by spontaneous collisions between the molecules of a liquid or gas, for instance.
- A positively charged ion and a free electron are produced as a result.
- Physical ionization is the term used most often to describe this kind of ionization.
- A new negatively charged anion may even be created if the free electron continues to attach itself to additional atoms or molecules.
- Chemical interactions are a significant additional method of creating ions.
- For instance, the atoms that make up an ionic compound like salt undergo dissociation and create free ions when the substance is dissolved in a suitable solvent (like water).
- Sodium cations and chloride anions are produced as a result of dissociation when common salt, also known as sodium chloride, is dissolved in water.
- It should be noted that the symbols for sodium cations and chloride anions are respectively Na+ and Cl-.
- Other significant ways that ions can be created include when direct currents are passed through specific conducting solutions and this causes ions to be created in it.
It should be noted that the ionization process used to dissolve anodes also produces a significant amount of free ions.
