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.
Here is the important thing: ONLY electrons can be lost or gained in normal chemical reactions. Since electrons are negatively charged, you can only become positive by losing them. Negative ions are created when a neutral atom gains additional electrons. The charge of the ion will be the difference between the two. (5 protons and 7 electrons will create an ion with a -2 charge). To get positive ions an atom must lose electrons so there aren't enough left to counteract the positive charge of all the protons.
