What is anion Negatively charged particles are called negative ions. When molecules or atoms in the air lose or gain electrons, they form charged particles called ions, such as sodium ions Na+; charged atomic groups are also called "sons", such as sulfate ions. Certain molecules can also form ions under special circumstances. Negative ions, also known as negative (oxygen) ions, refer to the oxygen ions that get one or more electrons negatively charged. The main components of air are nitrogen, oxygen, carbon dioxide and water vapor. Nitrogen accounts for 78%, oxygen accounts for 21%, and carbon dioxide accounts for 0.03%. Nitrogen has no affinity for electrons, and only oxygen and carbon dioxide have affinity for electrons. However, the oxygen content is 700 times that of carbon dioxide, so most of the negative ions generated in the air are air negative oxygen ions. It is formed by the combination of free electrons with oxygen molecules in the air. Discharge (lightning) phenomena, photoelectric effects, fountains, waterfalls, etc. in nature can ionize the surrounding air to form negative oxygen ions. Air negative (oxygen) ions are negatively charged single electrons and combined with other neutral molecular groups to form negatively charged particles. Negative ions are divided into large particle size, medium particle size, and small particle size. Small particle size is beneficial to human health In general, only the study of small particle size is concerned. In natural ecosystems, forests, waterfalls and thunderstorms are important places to generate (negative) oxygen ions.
