Virtually all particles in the air have a positive charge, while negative ions have a negative charge. In which case, negative ions and particles magnetically attract to one another. When there is a high enough concentration of negative ions in the air, they will attract to floating particles in large numbers.
Monatomic Ions. Ions are atoms that have either lost or gained electrons. While atoms are neutral, ions are. charged particles. Ã¸ A loss of electrons results in a positive ion or cation (pronounced âcat-eye-onâ). Ã¸ A gain of electrons results in a negative ion or anion (pronounced âan-eye-onâ). Although ions and elements have similar chemical symbols, they are entirely different. substances with different physical properties. A. Monatomic Ions.
