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.
1 Positively charged ions move to the negative electrode during electrolysis. 2  They receive electrons and are reduced reduction: Reduction is a reaction in which oxygen is removed from a substance. 3  Reduction also means a gain in electrons. . 4  Negatively charged ions move to the positive electrode during electrolysis. Reduction also means a gain in electrons. . 2  Negatively charged ions move to the positive electrode during electrolysis. 3  They lose electrons and are oxidised oxidation: Oxidation is a reaction in which oxygen combines with a substance.
