What is an Ion?

Ions are atoms or molecules that have gained or lost electrons, resulting in them becoming negatively or positively charged. They are the result of an electron becoming either added or taken away from an atom or molecule. This change, in turn, causes the charge of the atom or molecule to become ‘imbalanced’. Since the electron carries an electrical charge, the addition or removal of electrons can cause a charge to be created. The atom or molecule-with-electrons-missing is known as a cation, and the atom or molecule-with-electrons-in-excess is known as an anion.

Importance of Ions

Ions are incredibly important in a variety of chemical and biological processes. They are vital for not just the processes of life, such as respiration and nucleic acid production, but also for industry, such as in manufacturing and transport. Ions also play a role in helping to maintain balance within the body, as they are part of the electrical systems that help nerve cells communicate and regulate organ functions.

Applications of Ions

Ions can be used in a wide range of applications, from medical imaging and diagnostics through to large scale industrial processes. In medical imaging, the use of radioisotopes enables medical professionals to map the shape and pathways of tissue, helping them to identify diseases and develop treatments. In industrial processes, ions are used to form polymers chains and intensify chemical reactions, thus helping to produce products like rubber, plastics and electrical components.

Ions also play an important part in the disposal of waste, as ion exchange systems are often used to filter water by trapping unwanted ions and removing them from the water supply. Ion exchange systems are also used to remove pollutants from liquids.

In conclusion, ions are incredibly important for a wide range of applications, from biochemistry to industrial mass production. They can be used to help diagnose diseases and provide vital imagery to medical professionals, as well as help to purify water and remove pollutants from waste streams. As such, ions are incredibly useful tool and are almost everywhere in our daily lives.
