Understanding Ionisation: Processes, Applications, and Importance
Ionisation is the process by which a neutral atom or molecule gains or loses electrons to form ions. This can happen in various ways, such as through the interaction with high-energy radiation, collisions with other particles, or changes in temperature and pressure.
When an atom or molecule loses one or more electrons, it becomes positively charged and is called a cation. Conversely, when it gains one or more electrons, it becomes negatively charged and is called an anion. The process of losing or gaining electrons is called ionisation.
Ionisation can be used to purify water, air, and other substances by removing impurities and contaminants. It is also used in many industrial processes, such as the production of semiconductors, plastics, and pharmaceuticals. Additionally, ionisation is a key concept in fields such as chemistry, physics, and biology, and has many practical applications in fields such as medicine, environmental science, and energy production.
