We may also hear about ionization in relation to air purifiers, which use electric charges to remove particles from the air.In chemistry, ions are important because they play a crucial role in chemical reactions. They can be positively charged (called cations) or negatively charged (called anions) and are involved in forming chemical bonds.Overall, the word ion is used in scientific and technical contexts, and it is important to understand its meaning when studying chemistry, physics, and other sciences.
