How negative ions decrease

Home > Theory > What is a negative ion? > How negative ions decrease

Decrease for some reasons with unique interpretation of air ions

Negative ions in the air decrease or seem to decrease by:
1. Neutralization with positive ions
Positive and negative ions are electrically cancelled out.
2. Diffusion
Negative ions widely spread in the air, resulting the number of negative ions per cc (i.e. ion density pcs/cc) decreases.
3. Absorption by dust
This is applicable to air ions only. After absorption, the mass of the combined object (i.e. negative ions and dust) is much more than ions themselves and it is regarded that they are no longer ions (small ions). This is because it is generally understood that negative ions have small mass. Negative ions neither disappear nor lose the electronic properties.
