Cations and anions

Cations and anions are types of ions, which are atoms or molecules with electrical charges. Cations are positively charged because they have lost one or more electrons, while anions are negatively charged because they have gained electrons. These charged particles are essential in many processes, like forming salts, conducting electricity in solutions, and enabling nerve signals in the body. Their ability to attract or repel each other based on their charges influences how substances interact at the molecular level, playing a crucial role in chemistry and biology.
